Altar of Fangs — Mythic+ Guide
Aggregated from 30 top WarcraftLogs key runs (81 deaths studied). Interrupt rates show what the best groups actually kick — a priority list straight from the data.
This page ranks interrupts and deadly abilities in Altar of Fangs Mythic+ based on 30 top-ranked WarcraftLogs runs (81 deaths total). Kick rate is the percentage of times top groups interrupted a cast. Top groups prioritize Piercing Hiss and Toxic Atrophy at 92% kick rate each—these are must-kicks. High priority includes Envenom (62%) and Mass Envenom (72%). Fetid Spit (12%) and Dismember (7%) are rarely interrupted, so don't waste kicks on them.
For deaths, Laced Edge caused 10 deaths, Venom Burst 8, and Unstable Totem and Melee 7 each. Use this to plan your kicks: focus on the must-kick abilities to prevent the most dangerous effects. Remember, kick rates reflect player behavior, not necessarily spell strength—top groups may let some casts through because they're less threatening. When reading the table, note the tier column: 'must' means interrupt every time, 'high' means prioritize if available, 'low' means ignore unless nothing else to kick.
