You could have unlocked Combat Training in Last Hope. I'm not sure if you can get the category now. Five points in Thick Skin would give you 15% resist all. Also, I have a Shalore which is just about ready to leave for the far east and he's level 34. You could use the Far Portal to gain levels if you did not do so. I'm not sure it's any safer though.

Uhm just as a sidenote the overpowered wyrm is optional and you probably shouldn't attempt it unless you feel very strong in the other areas.

I'm not sure as to how you get killed so often by offscreen enemies sadly.

You should probably do the spider lair before the prides, its a bit easier.
And the wyrm after the prides -IF- you want to do it. Each pride has different types of monsters, try to target those with monsters that you can beat easily first (ex if you have high fire/water res, you could go for the one with the cryo/pyro-mancers)

As far as your character goes, I am amazed you got this far with your current equipment.
You don't have much elemental defense and crit which would be good with the 4 levels you have in corona (you should have invested a few points in the shalore crit bonus and blood red moon for it to proc more often)

Your current character relies on magic/spell power and cun/crit (spell crit) for damage.

You don't benefit from your belt (which gives mental crit, not spell crit), gloves which don't give you anything but resist to fire/dark) and your helm is a bit lackluster. Your boots give movement speed, might be useful for fleeing or moving in combat, or a specific place in the game... , but are a bit weak on your main stats, movement speed, just incase you didn't know, doesnt affect your casting time which still take a full turn. Edit - oh and your cloak seems to just give you 10 def/6 cun

I'm actually also not sure if your ring that does life leech works with spells (never tried so really just dunno).

I am having the same experience with anorithil every time i make one. As far as i can tell, their defensive options are just crap, and you usually end up dying to "kinda" high burst, stuff which other classes can just erect their regular defenses for and be fine. I dont have much advice for you since my anorithils start failing once they go east as well, but i can say its not you thats the problem, its the class ;)

First off, resists do indeed help even if you have a shield up. Damage is calculated (including resists) before it is applied, and then applied to whatever it is supposed to apply to (shields, mana, psi, health, etc). So yes, the 15% all resist would indeed help some. Maybe not a ton, but some.

Second, it's (nearly) impossible to be hit from off screen. Opponents don't react to anything further than 10 tiles away, which also happens to be the (normal) maximum sight range, unless damaged. Might be further than your light is casting if you're somewhere that is relevant, or they may be invisible, but they won't simply be outside of what you can see (this is compounded by the fact that there are only a dozen or so abilities that can even hit outside 10 tiles.)

Overall I'd have to say I agree with the others though. Looks like you're largely a victim of not particularly great equipment drops combined with the fact that Anorithil are possibly the squishiest class in the game. I've never gotten far with them, but it always seems they rely on nuking the opponent before they even have a chance to react, which isn't too hard before the prides, but the prides are the first source of serious ranged enemies you have to deal with in the game, thus often being the breaking point for characters which were otherwise breezing through the game.

Sorry guys, but that's off the mark. While it doesn't seem like it at first, Anorithils are far from squishy, just start using a shielding rune and Bathe In Light everytime you feel in danger, then enjoy some 2k shield on you. Every time you get the Light tree on a character you should always aim for at least 1/5/1/5. Healing Light is decent but not really worth some investment in it unless you got spare points. Barrier is just bad, as it wastes a turn and, while it can last 10 rounds, it will never do so as its base value is laughably low. Bathe In Light and Providence, on the other hand, are pure unadulterated gold. Also, Chant of Resistance + Thick Skin grants you 40+% resistance to all damage.
As for things damaging you out of LOS, yeah, you need either high light or infravision. Do note that Sun Flare, staves of illumination and Hymn of Detection are all good fits for that purpose.
Another thing, choose your main Hymn and main Chant beforehand and don't invest into any other ones, ever. Points put into other Chants or Hymns are just points you wasted.

You could look at my Anorithil win for more specific info, ( http://te4.org/characters/19173/tome/95240fcc-1df7-4e07-9657-50269367eca3 ) it did die against Linaniil but that's because I made some silly mistakes. Also, I had swapped some equipment out as I completed the game with the black robe and the staff of destruction, since as a Corona/Moonlight/sure spell crit build I wanted as many spell procs on as I could manage and, believe me, it was glorious.

I admit I usually ignore bathe in light because 1) it can heal your enemies and 2) the amounts are painfully low early on and I didn't realize it scaled up so well.

May have to try an anorithils again in 'light' of this new information, though I often die in that first boss encounter, it is surprisingly difficult.

Still, if the OP isn't doing this (and he isn't) then he is still squishy.

My confusion has cleared up a bit after retrying.

Had a really good early run only running into trouble with the Grand Corruptor whom I left alone after dying once.

Went East at level 30ish, cleared Spider easily (thanks to the staff of destruction), emptied out the Vor Armory (skipping the wyrms of death room), Killed the Wyrm to get the diamond and headed back west where I proceeded to fail against several of the backup bosses. Apparently shields are not all that vs some bosses.

I was pretty angry after my last death. (Still have one life left but am done with that character since I want to use the vault and I have a good deal of interesting items.)

Things learned thanks to varying bits of advice:

 - Equipment is very important for survival as an Anny. Shields will only take you so far. You also need to maximize what advantages you get.

 - Blood Moon/Corona/Shalore whatever it is that gives you crits at 5 points each is very important.

 - perhaps getting Con to 50+ isn't such a great plan. Next time I will focus more on Cunning.

 - Don't forget to PD when a meleer draws you in. That failure cost me two lives at least.

 - Don't forget to use your esp/telepathy items if you find some to ambush your enemies. 

I didn't die to being ambushed this character but I have in the past and I noticed that Auo explore while useful at times can be hazardous. Particularly in the Temple of Creation. because Mymidons are no joke.

Died once in a vault to 3 luminescent horrors + a few other guys all hitting me hard as I rounded a corner. Instead of trying to flee, I put up a shield which did no good at all as the massive damage done by all monsters was well over the shield (450+ hp) and my current health (about 900 hp). Needless to say I didn't die again during this game.

Considering I had a vial of blood I probably would have finished this game on roguelike if I had played that instead. I will have to give that a go at some point.

Thanks all again, for your invaluable advice.
