Is the King Slime Set good? Rating by build
For each build we take the strongest loadout (gear and food), swap in the King Slime 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 | 70.9 | #20 | Core Commander Armor Set |
| Ranged | 65.7 | #29 | Mold Set |
| Magic | 67.8 | #21 | Arcane Monk Armor Set |
| Summoner | 48.2 | #20 | Chieftain Armor Set |
The King Slime Set fits melee builds best (#20 of all sets). It is a lower-level set, so even if it is strong when you get it, you will usually upgrade it or move to a higher-level set later in the 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.
