Lance

Few questions:

Physical attack normally also increases skill attack, but lance's skill only increases physical, correct?
Also, does it give +30 crit rate or +30% damage when he crits?

Another thing is a lot of his power seems to be fluff. My adam is 14m at half angel 3, but with my adam's set and equips, lance is at 19m with no saints. Both are at 8 stars.

Contrary to what is said in the skill description, his skill attack's damage is increased as well.
Don't know about the crit rate, but it increases for sure.
Overall, his skill attack is around one and a half more powerful than bloodstorm's attack at full health.

I think his crit rate might be increased... I seem to be able to crit on cerb and baal with him now, but so far I have only seen physical attacks crit. No idea how high the skill crits like.

He can crit quite high with his skill as well , but you need a decent lvl sword and spirit and some +skill attack jewels to help him out plus LB set is even better then add herja to keep his morale up.

Physical attack increases the strength of skill attacks, though not as much as skill attack would. Lancelot's critical stat is increased by 30% while Greater Savagery is in effect.
