Goon Temporal Warden Guide 1.1.5
Tips
Right, when it comes to TWs, you want to go exclusively bows with the strategy of going FAST AS FUCK and filling anything in your path with fuckloads of arrows. Shalore are a great race for this because of Grace of the Eternals and Timeless, which combined with Haste make you FASTER AS FUCK for longer.
For stat distribution, I maxed out dexterity first, then magic, then remaining points into willpower. You should also be putting at least one point into con per level until you can 5/5 Thick Skin (with buffs)
Early game, I focused on the Archery/Archery Prowess tree, branching into the Speed Control tree for Haste when my magic allowed it. After that, some skills you probably want to grab are Displace Damage and Damage Smearing for defense, Echoes from the Past for damage, Invigorate for cooldown reduction and stamina regen, and maybe Quantum Feed to make your Hastes more effective. I also found Slow pretty useful.
One thing I would recommend doing is keeping a good staff in your offslot to boost your spellpower whenever you cast a spell. Since just one point in Celerity lets you switch between your main weapon and your offslot instantly, there is no downside at all to doing this.
