How to deal with Gremlion ?

[ender]

Physical damage resistance>90% is what count in boss fight.
Paladins and Knights are good because they have ~30% physical resistance+ 40% from stone skin + 7% from medals = 77%.
You need another 15% from artifacts (boots, cuirass, dress).

With 92% resistance you take 8% from 4000 damage=320 dmg or 160 with mage shield.

Only Zigaldis need magic protection - for his area attack, fists are physical- but are more artifacts for that than for physical damage (and frog need poison, but is easy).

Royal Griffins (50% magic resist) are good for towers, but not for melee against zigaldis.
Demonogists (30% magic resist) for damage against Zigaldis.
Red dragons for no retal fire attack.
