looking for suggestions on crosspath summons

[Ragnarok-X]

Can someone tell me the unit command to make a unit eat more supplies ?

In addition, how exactly does fire shield work ? Say i make it fireshield 3, how is the hit and damage calculated ? Does the attacker roll a dice if the fireshields hit him only when he attacks or does he need to hit ? What the exact formular for fireshield attack / defense and especially damage ?

I finished the N/R summon. Its called Tribal Brute and is a human-sized hulk and is basicly a human thing under too much nature/fire magic influence. It got some mutations and is now a raging brute, think werewolf x2 but more cool. Likely N2R2 or N3R2.
