Aberrant Spectre

“A hooded wraith trailing clouds of toxic gas. Breathe it in and you will wish you had not.”

Fighting it

• It swings back once every 3 of your combat inputs, whether your attack hit or not.
• A kill is worth about 8,800 Melee or Ranged XP, or 12,100 Magic XP, plus about 2,937 Hitpoints XP. XP is paid per point of damage and shared out by your stance (a stance that sends half to Defence pays it at Defence's rate of 8). A finishing blow that overshoots adds a little more; poison and Vengeance damage pay nothing; XP bonuses from gear and food add on top.
• Its hits roll from 0 to 26 (half its Strength, plus one). The prayer Spellguard blocks them completely.
• Soft or unarmoured: Melee and Ranged tear in; Magic only lands normally.
• Putrid: each of its hits that does damage has a 30% chance to poison you. Plague-touched food (auto-eaten in combat) or an antipoison potion keeps it off, and putrid monsters can't be poisoned themselves.

Slayer

• Assigned as a task by Karst.
• On task, each kill gives 4,400 Slayer XP (4× its hitpoints).

With the Slayer unlock Bigger and Badder, an on-task kill can bring out its superior form, the Abhorrent Spectre.

Drops

Every row rolls on its own, so one kill can drop several things. Drops go straight to your bank (a pet goes straight onto you). Gear and potions that raise your rare find chance don't change these odds.

1/128 of kills also reach into the rare drop table.

After a kill the next one appears 2.5 seconds later. Dying costs nothing but time: a 15-second wait before you can fight again. The Agility perks Hot Pursuit and Second Wind shorten both (see Combat).
