Sentinel/Protector sounds more suited for a Skill Book rather than a Talent. Remember, Talents are passive abilities.
Stinkly cloud is way too debilitating for allies. I don't think we should make that idea happen.
Quick Reflexes / Awareness / whatever you want to call it, a Talent for +10 initiative - need more opinions on this. Is it OP? Underpowered? Should have additional perks or keep it simple?
Quickdraw sounds good, I'm all for that. Would open up really interesting hybrid playstyles.
Ugly Duck doesn't make sense to me. Besides you've already got Leadership perks to buff your allies.
Looking at the OP, Grounded looks like another candidate for the "buff this talent" category. Much like Ice King and Demon, it should probably have an additional side-effect. Perhaps Ice King ought to grant a buff to magical armour (instead of physical armour) and we'd relegate the physical armour buff to Grounded?
About Protector and sentinel, it is not a skill book to me, but a talent : 15% chance to block for a skillbook sound not valuable even if it cost 1 AP. And made a skill book with 100 chance is too op to me.
I think stinky cloud isnt too debilitating, but just make you thinking differently before going in figh/build your heros. I think its a talent I probably could take if it ll be in game.
A talent for intiative sounds good to me. if you want to make some strategic moves/actions before intiating fight.
For example, intiate fight with a mage with "stinky cloud" and "Awareness", you move away from your allies, avoiding debilitating abilities + positionning to figh effitiently, think its nice combo.
Moreover, a tank cant be overpower, because if you have one in your team with "sentinel", you need to be close (4m) to your mage too over protect him. In that case you got constitution reduction.
In this sens its work well because you can really crush your ennemies but you need to be strategic. If you go like a horse, choose other talents.
Ugly duck make sens to me for building a support for example. I think there is not enough talent to modify your way to play : today you play a magical hero : you take "far out man", "glass canon", "savage sortilege"... What about doing things differently ? Combine "Ugly duck" with "stinky cloud", and "the pure", you can stay back, healing / cursing soil / blessing your allies (not your enemies cuz of sight reduction). Combine "the pure " with "irritating genius" and "one man army" you get a tank healer. Combine "stinky cloud" and "speedcreeper", "guerilla" you get a sneeky assassin. Combine Leech, sentinel, and picture of health and you got a pure tank. "the pawn" and "awarness", "hothead", a great engage.
Anyway, its my way to think
