Sacred Heart

Guide

What is the Sacred Heart?

The Sacred Heart is a passive buff item that you keep inside your backpack. While you carry it, it grants several permanent bonuses to your character — such as experience, loot, HP/Mana regeneration, potion/spell healing, training speed and faster stamina recovery. You start with the base version (T0) and upgrade it through tiers (T1 up to T10) by merging two hearts of the same tier.

Use the !sacredbonus command in-game to see the full table and the training duration at each tier. The bonus only works with the Sacred Heart inside your backpack.

How to Obtain and Upgrade

Step	Description
1. Craft the Baseline (T0)	Craft the base Sacred Heart in the Craft System (category Enchanted Items). Cost: 50kk gold, no extra ingredients. Keep it inside your backpack to start receiving the tier 0 bonuses right away.
2. Merge	To upgrade a tier, use one Sacred Heart on another of the same tier (both must be in your inventory). Each attempt costs 50kk. On success, the two hearts become one of the next tier.
3. Failure Chance	Higher-tier merges can fail. On failure, only the gold is lost — your Sacred Hearts are not consumed. See the success rates in the table below.

Merge Success Rates

Upgrade	Cost	Success Rate
Baseline → T1	50kk	100%
T1 → T2	50kk	100%
T2 → T3	50kk	95%

The Sacred Heart must stay inside your backpack for the bonuses to work.

The Train Skill and Exercise Speed bonuses speed up training with exercise weapons — use !sacredbonus to see the exact duration at each tier.

Each value is cumulative per tier: the higher the tier, the greater all bonuses.

In-game command: !sacredbonus (full table and merge rules). Related house buff: !housebonus.

The heart in practice

The item sits in your backpack and the bonus shows up in its own look text. To raise a tier you merge two hearts of the same level; if it fails, only the gold is gone.
