Level 135 boss · 32,000 health · Heartwood Hollow · Three adventurers recommended
Heartwood Hollow
Look for the signed woodland cave near −659, 524, southwest of Pioneeria. Its ladder opens into a safe, lamp-lit vestibule; the round chamber to the north belongs to Stormroot. Bring a light and supplies. Three well-prepared adventurers are recommended, but there is no required calling or formal party membership. Five players can join, and additional helpers share the same encounter rather than receiving extra reward rolls. Players cannot attack one another here.
The living heart
32,000 health · Armour 24 · Defence 28. Its stone fists deal 65–130 before your defences. Warning damage uses the same adjusted-health rule as other major bosses: half the extra base health above balanced Ranger training is excluded, preserving the benefit of health-focused training. Equipment health remains included. Armour reduces these warning hits slightly.
- Bough cleave: a broad forward cone locks onto the floor for 1.8 seconds. Step out of the marked tiles before its 32% adjusted-health hit. Turning afterward does not move the warning.
- Branching roots: three root lanes warn for 2.2 seconds, then strike marked tiles for 28% of adjusted health. Step sideways into the gaps. Root attacks continue during the amber-knot phase.
- Amber knots: three knots shield the heart for up to 20 seconds. Stormroot takes only 25% damage while shielded. Split up and destroy all three; any weapon works. They have 900 health each and give no separate loot, experience or contribution credit. Breaking all three exposes the heart for 10 seconds, giving 35% extra damage.
- If knots remain: they disappear, the shield ends, and the outer ring warns for 3 seconds. Move into the marked inner safe circle near the heart; remaining outside takes 35% adjusted-health damage.
Warnings keep their full dodge time as the fight speeds up below 65% and 30% health. A shield fighter can use Challenge to draw close blows, a mender can repair actual injuries, and damage specialists can split the knots. These are useful choices, not compulsory roles. Retreat south to the ladder whenever needed. If every fighter leaves, pending attacks are cancelled; if every fighter leaves or falls for 10 seconds, its health and contribution reset. Attacks from the vestibule, boats or cliffs do not damage it. Building and Bank Box are disabled inside the hollow.
One shared hoard
Item eligibility requires 3% of full boss health in contribution: 960 work. Damage to Stormroot counts, plus half of effective healing of other fighters' injuries caused by Stormroot. Overhealing, self-healing and unrelated injuries give no support credit. Passive proximity and a small last-second tag do not qualify for items. Qualified helpers receive shares weighted by actual work; weaker contributions still remain in the denominator, so they cannot inflate another player's share.
One victory rolls 1200–1800 coins, 6–9 mushroom broth, 6–9 greater health potions and 6–9 greater mana potions for the whole encounter. The cosmetic Stormroot heart has one chance in 30 per encounter, with one contribution-weighted recipient at most. Build it into a Stormroot trophy for your home; it gives no combat bonus. More players never multiply the hoard or the character-XP pool. Earned character XP is split by work, with the ordinary combat-level reward adjustment.
The rare Heartwood focus has one chance in 120 per victory for the whole encounter, with at most one contribution-weighted recipient. Requires Magic 85 and extends Shared Healing from five to six tiles at normal mana cost; Renew stays at five tiles. This equipment roll is separate from the decorative trophy.
Collect at the heart altar
After victory, stand within 3 tiles of the central Heartwood altar, on foot and out of combat, and choose Collect rewards. Earned XP, Journal credit and items persist through death, logout and server restarts. A full bag does not lose your share: XP and Journal credit can be collected, and unfitted items wait for another visit. Collection cannot pay twice. The colossus can return 30 minutes after defeat.

Ordinary items, coins and rare finds come from one shared hoard. Contribution determines your share or your chance to receive a single item; the 3% threshold grants eligibility, not a full extra roll. Drop rolls are chances, not a promise per trip. Defeat it to record it in your in-game Creature Journal.
