Recomended Characters
| Character | Explanation |
|---|---|
Rebecca | - The bonus to Skill Range increases the AoE pulse size of Rebecca's summons, but Siren's Kiss has the same bonus while providing additional benefits. So we generally recommend that weapon over this one. |
Hellfire | - Having additional Skill Duration helps Hellfire maintain her active buff, which she relies on as her primary source of damage. |
