Very nice interview! In particular, the story of Kellan's Taunt reminds me of
Sore Losers, where the protagonist Markus could shout "WTF Are You Doing?" and get
every enemy Berserk and unable to use skills. It was really fun and useful, but it both made the other two Berserk-causing skills irrelevant, and broke the game quite badly (though the weak balancing where latter-game armour reduced enemies' attacks to around 5 damage while you could exploit Taser's +25 attack bonus to deal ~60 had a lot to do with it as well). It's good that you've managed to iron out stuff like this, eventually.
