I also played dota for four years, so it comes naturally to me. When I see a character's name I know what they can do.
That's the reason I made the faulty first read on Abaddon tbh. In the game, he casts his shield on an ally and it absorbs a fixed amount of damage. Once that damage is dealt the shield explodes damaging people around. That's why I thought Abby has some kind of secret attack initially.
But Ulli changed the ability a bit to fit this game.
@Desi : I ignored the "perchance" part at first. If anything, it hints you're Mortred and not Abaddon, since Mortred passively has 1/3 (33%) chance of dodging day attacks on her.
