Burst Damage

You need the following to craft all six items: 2 Ground Death Blossom, 2 Ground Rising Glory, 2 Ground Marrowroot, 2 Ground Vigil's Torch, 2 Ground Widowbloom, and 13 Siren's Pollen, 8 Riverbud, and a Crystal Vial for the potion. The five Burst items and their recipes drop from clickable mushrooms in Korthia at very low rates, so purchasing them from the Auction House is a viable alternative; the Potion of Bursting Blood recipe is learned for 30 gold.

Craft Blossom Burst, Glory Burst, Marrow Burst, Torch Burst, and Widow Burst from their respective Ground reagents (2 of each), then craft the Potion of Bursting Blood. Each Burst item has 5 charges and is tradeable, so one set of crafted items can be shared across a group of five players.

This achievement requires a group of 5 players — each player must target the same single player and use their Burst item on them, since each Burst only applies its buff to one target. Once that player has all five Burst buffs active (each lasts 30 seconds), they immediately drink the Potion of Bursting Blood to earn the achievement. Repeat every 3 minutes for each player in the group.

To solo this achievement, place all six items on your action bar, position your character in an old zone to reduce loading time, and disable unnecessary addons for faster loading. Use one Burst item, then log out immediately — the 3-minute cooldown continues ticking while logged out but the 30-second buff does not expire. Log back in just before the buff would run out, use the next Burst item, log out again, and repeat until all five buffs are active simultaneously, then quickly drink the Potion of Bursting Blood.
