I think its a good idea to add a special effect to 'reinforcement' when wielding a 2h with shield (ogre moment)

The talent doesn't mention it, so I'd assume no but maybe you just didn't include it in description. Its a valid target for it, but that's probably because its a summon spell. Also a suggestion, you could make changes for the 'Great caller' Mindstar ( https://te4.org/wiki/Great_Caller ) (if you havent yet). It's stats seem like they would be useless when all the summoner changes in this addon are considered. And ofcourse, great addon!

Enjoying the addon alot. And actually made me play summoner. Though I wonder for iron blood and sand sustian talent and it's brother commune with nature. Since I tried to get some skills in the latter tree for it defensive passives and sustain (and more defensive style to not rack up large amounts EQ outside of meditate). So I switch in between them. Problem is that it takes two turns (as you can't activate the other with one turned one and turning off takes a turn.) Though I have probably been looking at as a stance system which I probably shouldn't.

But as went about playing. Attack order doesn't and yet sometiems work. Even if I have summons within my sight range it literally says I need summons to use attack order. As in summons would be out and choose a target but literally says "I have need summons to use it"

I have to say, I really like this addon.
I've only tried a plantmancer so far, might do a "single summon" run with Companion Hound later.
After an untimely death, I sadly had to retire the character but did some more testing in devmode.

What I found out:
a) Gardener of Eyal can go really nuts. (it goes to 2 cd between plants with Adept + mastery boost, which is great)

b) Blighted Summoning makes your flytraps behave weirdly. It gives them Poison Storm, which they usually won't ever use without Through the Crowd due to friendly fire. (won't use it as long as any ally is in range)
The notable exception here is the World Tree, which will freely use it for some reason.

c) (this one's not on you) Poison Storm ignores Through the Crowd, as I found out when I turned it on and all flytraps promptly used the skill, killing each other and me in a few turns.
I'd say you should give flytraps another Blighted talent (same for ivy and the World Tree, since they get the same one).

d) Companion Hounds are affected by Strengthened Bond despite it not saying so.

Hey, great work here! I really like this implementation of a wild summoner. Standard summoner I feel is too hands-off, with little to do besides plop down summons and wait. This adds a lot of interactivity, which I really enjoy. The fact there are three distinct "paths" to choose from with ranged, melee, or pure summoner, plus the choice between maintaining lots of summons or cycling though them quickly, creates quite a variety of builds, which I also really enjoy. All in all, really great work!

There are a few issues, all of them pretty minor.

1.There are a few talents that say deals "damage" without specifying a type. Are these physical damage?
2.Learning the ranged weapon mastery does not teach you Shoot, which is a bit of an inconvenience. I was also a little put off seeing the weapon trees are locked until level 10, but it didn't actually turn out to be much of an issue.
3.The Bear knows Warshout, but I haven't seen it use it. If it's the same Warshout as the 2-Hand attack tree, it requires the user to be wielding a 2h weapon, which could be the issue?
EDIT: Looks like the bear can't use any of it's talents, actually. Seems it has the talents Minotaurs would have, but Minotaurs are summoned with a weapon to use them. The bear could use brawler talents instead, maybe?
4.If you learn and then unlearn Companion Hound, you continue to summon companion hounds even though you no longer know the talent.
EDIT: The companion hound stopped appearing after I changed levels.
5.Gardener of Eyal is a bit of a mixed bag. The plants get summoned near you, which is often out of range to be useful at the start of a combat, and then they sit there using up a summon slot. The lack of control over when a summon will appear when you can only have a limited number is a bit of a nuisance. I might prefer it switched with the last talent in the tree, so I can decided when and if I want them without having to take the talent in order to get to Phase Summon.
EDIT:Not sure if it is intended or not, but Gardener does not place Venus Flytrap on cooldown when it triggers. It seems that all of the other talents that trigger a summon, like Bite Them, do put the talent on cooldown.
6.Some descriptions could use clarification. I'm not sure exactly what the effect of World Tree is, for instance. Sometimes it triggers other summons, but not always?
7.Really minor, but capitalization is inconsistent in talent names.
8.When using the first Ranger attack, Bite Them, you get a Lua error if you target an enemy out of range:

Just want to say once more that I really, really like this rework. I've started a Ranger run, and I can't wait to try Dragon and Clan, too. Great job!
