He has a decent chance of defeating Arec. The main thing is to give him a two-handed weapon. Or a katana. And some items for HP and dodge. He will deal 210 damage (taking armor into account) for each miss. That is, five misses from the lizard will be enough for victory. Four, if you also buy gloves. Agama will need 2-3 hits, but the chance to hit is only 12.5% (without bonuses to dodge from items).
