Presumed images of the three bosses

⬥ NM has a safe death mechanic, but players will suffer from "Resurrection Sickness". Upon death, the player is immune to damage for a while, but will deal severely reduced damage.

⬥ Sanctum bosses are likely to have high defence.

‎ ‎ ‎ ‎• Sidetrack: The new masterwork sword (requiring 99 attack) being T100, to be released after Sanctum, ties into this.

⬥ The Sanctum will use more tile-based telegraphing (the gif itself is called telegraph).

Dark beast-like (Devourer) boss

The only shown arena and boss so far.

⬥ Players enter by jumping off a bridge into an intricately coloured arena with two (soul) obelisks on opposite sides (tile visibility varies per image).

T95 magic dual wield weapons

⬥ Have a special attack spec

‎ ‎ ‎ ‎• Synergises with the passive effect or DoTs in general

‎ ‎ ‎ ‎• May require both MH and OH

Mainhand and offhand have a passive effect for one and two items equipped (passives swapped).

⬥ Passive (1): Damage over time abilities generate Essence Corruption with each hit:

‎ ‎ ‎ ‎• 1 Essence Corruption stack: Essence Corruption stack: Your damage over time abilities have a 30% chance to empower, dealing the damage instantly and refreshing their cooldown.

‎ ‎ ‎ ‎• 25 Essence Corruption stacks: Deal bonus damage against enemies (100% of stacks + 100% of your Magic level).

‎ ‎ ‎ ‎• 50 Essence Corruption stacks: Basic abilities generate an additional 3.6% adrenaline over 6 seconds.

⬥ Passive (2): Damage over time abilities deal 30% more damage, affecting comb and corruptblast

⬥ Maximum stacks: 100.

NO charging on weapons

⬥ Losing stacks when switching weapons is still up in the air.
