Root

Root has 20 health.

It takes extra damage from fire; it resists frost; poison does nothing to it at all. Blunt, slash and pierce land at full damage, so that is what to bring.

Nothing but a player can damage it, so tames, Dvergr and summoned companions do nothing for this part of the fight.

It has one attack, 55 blunt.

Of everything craftable, Thunderblood Crossbow, Lightning Strike and Staff of Embers put the most damage through what it resists.

Root is the immobile tendril The Elder pulls out of the ground during his fight, 15 at a time inside a 15 meter circle centred on a player. It has 20 health, walk and run speeds of 0, is weak to fire, resists frost, and is immune to poison and to damage from any source that is not a player. Every 3 seconds it can slam a player within 4 meters for 55 blunt plus 20 chop and 20 pickaxe. Roots despawn after 18 to 20 seconds or the instant The Elder dies, and they drop nothing.
