The player stacking on-death and on-hit attributes in games where character death doesn't result in loot drop, performing suicide attack against high-value target.

This tactics is usually used against boss monsters, using high-level on-death attributes(such as AoE spells cast on attacks) and minimal defenses sufficient to get close to boss monsters. The usually tanking players are often used to distract the boss and leave during the attack duration.

Groups of players may resurrect each other to reduce down-time(such as coming back to boss area) or body-retrieval, to speed up the process of such attack.
On-death attributes are also enhanced by other players debuffs with a coordinated attack keeping the target in permanent debuff/life drain state to make it more vulnerable.
