Pick a companion on the left to see what it brings to your build.
Companion Bolster
Every companion you own adds to your Companion Bolster, and the amount depends on its rarity.
Only your best 10 companions count, so the ceiling is 120% —
exactly ten Celestial companions. Bolster multiplies what your summoned companion contributes to
your item level, so raising it lifts every stat that item level feeds.
| Rarity | Bolster given | Ten of them |
|---|
| Common | 0.5% | 5% |
| Uncommon | 1% | 10% |
| Rare | 2% | 20% |
| Epic | 3% | 30% |
| Legendary | 5% | 50% |
| Mythic | 10% | 100% |
| Celestial | 12% | 120% (cap) |
100% is the baseline, not the maximum — the bar runs to 120%. You can read your own figure on the
character sheet, next to the companion item level contribution.
Mounts use a separate bolster with its own table and a 125% ceiling.
