Tips and Details

• Transforming between G-Skill Mode system puts every currently equipped G-Skill on a 1-second cooldown, except the one that is being transformed to, which can be cast half a second after transforming.
  • You cannot switch while midair or casting skills, but you can switch while running.
  • The switching does not provide any kind of  Self BuffSuper ArmorSelf BuffSuper Armor or invincibility during casting, thus being easily interruptible. However, the buffs will always apply, even if interrupted.
  • The motion does not have any time stop and is the same for all skills except G-Ex Ancient Buster that also has freeze frames.
  • Bug: accumulating stacks will not work if switched instantly after the G-Skill went off cooldown.
    • However, the cooldown effect will still work.
• The cooldown effect does not have a reactivation cooldown, other than the one when switching between G-Skill Mode system, making it extremely effective, especially when used in between of other skills, reducing their cooldowns right as you switch.
  • It is also very well compatible with other passives on this path, such as G-Mastery, ensuring that you keep all your buffs up at all times.
  • The cooldown decrease is calculated based on the original cooldown of the skill, ignoring all Cooldown Reduction effects or stats, except for Skill Traits. For example, Heavy Magnetic Generator's cooldown will always be reduced by 3.17 seconds, ignoring the cooldown decrease from G-Mastery which mitigates the Heavy trait. Because of this calculation method, getting additional Cooldown Reduction from any other source such as El Resonance does make your cooldowns even speedier.
• It is recommended to only sparingly use G-Skills in dungeons due to them locking you out of the ability to switch the G-Skill Mode, which makes you unable to refresh your buffs or reduce your skill cooldowns.
  • One should consider bringing only 2 G-Skills to allow for switching, preferably ones that have short downtimes of being able to switch again, for example G-3 Raptor due to its short cooldown, [Mod] G-2 Rolling Thunder due to being able to switch right after casting, or [Mod] G-1 Corona due to both.
  • Due to the buff's short duration, it can expire during cutscenes. To maximize its duration, it is recommended to switch the G-Skill Mode right before one.
    • However, this might be confusing if you don't remember which skill you are currently switched to, but you can't see your skill or buff bar anymore. The safest technique to refresh the buff is to trigger a skill that allows you to switch right after casting, such as the aforementioned [Mod] G-1 Corona or [Mod] G-2 Rolling Thunder.
• The Transform Standby attack of each G-Skill will also trigger Howl in Altar of Invocation's first two phases if the respective skill tier is currently blocked, so use it with caution.
  • This also applies to G-3 Raptor, which however is an Active skill rather than a Special Active, so it is never blocked. It is recommended to use this skill's Transform Standby to initialize your passives in order to avoid extra Howl patterns.
