Hot damn, Sima Yi is insanely strong in this game. I distinctly remember back before I began even playing Warriors Abyss all the posts saying that Sima Yi can carry players to T5 easily. Well, I now know they weren't exaggerating.

>i can only equip two treasure (plus saddle) right now but in WO3 screenshots I see more slots open up. I assumed that was something tied to some progression mechanic.
Oh that. Yeah, you need promotions. You get two 2 extra slots after your first promotion and another 2 after your second promotion. In total, you max out at 6 slots after 2 promotions.
