Pikel’s common helm regen is not stacking with warrior taunt regen.
Also, the character is badly thought out for normal content. His legendary helm works for 4 turns, nothing for 5 as it has 9 turn cool down.
His epic regen is 2 turns then nothing for 3 due to 5 turn cool down. This limits his ability to level and be taken on the team as the healer.
Please review this and also how to gain experience as the xp spellbooks are far too low max.capacity. This means you do not sell new characters. Please implement bonus experience at 300% until within 2 levels of your main party. Also, let us win and stack xp options which we can use to power level new chars - then we will want to buy them.
