Gjall has 1,500 health and spawns in the Mistlands.
It resists fire; spirit does nothing to it at all. Blunt, slash and pierce land at full damage, so that is what to bring.
Its hardest hit is spit at 80 fire and 50 blunt, out of 2 attacks.
Some of what it throws is elemental, so fire resistance is worth having.
You cannot block shake, so give yourself room to dodge instead.
Of everything craftable, 
Frostfire Crossbow, 
Thunderblood Crossbow and 
Lightning Strike put the most damage through what it resists.
It always drops 
Bilebag.
Gjall is a flying Mistlands creature with 1,500 health that resists fire and is immune to spirit damage. Its egg sacks are a weak spot that takes very heavy pierce damage, so arrows into the underside kill it far faster than anything aimed at the body. It spits two fireballs for 50 blunt and 80 fire every 6 seconds from 6 to 30 meters and drops three eggs that hatch into 0-star 
Ticks every 50 seconds, but both attacks need range: standing directly beneath it disables them and leaves only an unblockable three-hit sway for 20 blunt each. It always drops a Bilebag, with the 
Gjall Trophy at 30 percent.
Shoot the face. It hovers slow and predictable, so ranged damage wins while you sidestep the twin fireballs. Kill the dropped ticks first or parry them off you; pierce resistance armor helps against them. If the stamina bar allows, you can simply outrun the whole encounter.

Each 64 m zone keeps its own timer per entry and rolls the chance once per interval while loaded; a zone never loaded before rolls the moment you arrive. The spawn lands 40 to 80 m from a player, never inside a base unless noted, and "max near you" counts the loaded area around that zone. Dungeon and camp spawners are separate and not counted here.
With devcommands enabled, this spawns Gjall in front of you. The third number is the level: 3 spawns a 2-star.
