About | Raising Weapon Skills

---

Weapon Skills are modifiers found on Rare and higher weapons. These skills give stat bonuses to certain types of characters, or provide other bonuses based on the skill.

Most weapon skills have 2 parts: the base skill, and the skill level. The base skill has a fixed effect, such as "% boost to allies' ATK," and the skill level amplifies the effect by increasing that base percentage. For weapons with maximum levels of 100 or lower, the maximum skill level is 10. For weapons with maximum levels of 150, the maximum skill level is 15. For most weapons, each skill level from 1-10 increases the base effect by 1%, while each skill level from 11-15 increases the base effect by less than 1%.

There are some skills that require the weapon to be a certain level. This naturally also requires the weapon to be uncapped enough for you to reach that level. Refer to individual weapon pages to determine if that weapon has such a skill. The skill level can be raised before that point.

Each party uses 1 main weapon and up to 9 sub weapons. This is colloquially referred to as the "weapon grid." The main weapon dictates the element and charge attack of your main character, but weapon skills on all weapons in your grid are always active (apart from a few exceptions specifically stating so) and will strengthen all applicable characters in your party.

Weapon Skill Types

There are 3 weapon skill types:

• Normal - Generally found on Draw and older event weapons.
  • The Normal type includes Normal II weapons and Bahamut Weapons.
• Omega - Found on weapons named after the Omega raids.
• EX - Also referred to as "Unknown" weapon skills. Found on collaboration and newer story event weapons. For high-level players, Xeno Weapons and Rose Crystal Weapons are also available. As of November 2016 with A Peace of the Pie, new story event weapons have EX weapon skills unlocked at level 100.

The three skill types modify their own multipliers and can be boosted by certain summons:

• Normal skills are boosted by Premium Draw summons, specifically Agnis (fire), Varuna (water), Titan (earth), Zephyrus (wind), Zeus (light), and Hades (dark). These summons increase skill power by +80%, increasing to +120% at 3★
• Omega skills are boosted by the element's respective Omega summon. Starts at +50%, increases to +100% at 3★
• Mysterious skills, a type of EX skill from IDOLM@STER collab weapons, are boosted by the Ranko Kanzaki summon. Starts at 30%, increases to 50% at 3★, and increases to 66% at 4★
