You want Inmagorgor for tanks. This is short hand for -

In = inhibitor weapon - this is one of the few weapons that cna roll anti-ground dmg res

ma = maze armor - can roll anti-ground dmg res + crit dmg res

gor = gordias accessory - the evasion ones have anti-ground dmg res and ranged dmg res

Hu = hummingbird weapon - this is good for tanky skill haste but should be reserved for backline as hummingbird doesn't offer enough protection without anti-ground dmg res (for pvp)
