Is the Hydra Jewelry Set good? Rating by build
For each build we take the strongest loadout (gear and food), swap in the Hydra Jewelry Set pieces (with the set bonus) and calculate the damage. Damage is relative to the strongest loadout (= 100), and the rank is out of all 70 sets.
| Build | Damage (best = 100) | Rank | Best set for this build |
|---|---|---|---|
| Melee | 64.4 | #33 | Core Commander Armor Set |
| Ranged | 60.4 | #45 | Mold Set |
| Magic | 66.0 | #22 | Arcane Monk Armor Set |
| Summoner | 43.2 | #28 | Chieftain Armor Set |
The Hydra Jewelry Set fits magic builds best (#22 of all sets). Its level holds up in the late game.
Damage assumes endgame gear (Lv.20) and skills at level 100. Defense (armor, health) is not included; compare the totals above for that. The damage model is this site's own estimate, not an official formula.
