The α branch is for non-explosive RPGs and β is for explosive type. Attempt to use β branch for non-explosive RPGs will reduce its effectiveness and vice versa.
When using β for multi-stage RPGs such as Tyr's War Blade or certain weapons that have slow enough flight speed to trigger "Extra Rewards", it will cause infinite loop of warheads without consuming additional ammo.
Multi-stage or multi-warheads (include buffs) when fired from β skill will fires multiple projectiles as if it was fired from the weapon itself.
Switching to other weapons while in infinite loop of warheads does not disable β skill.
β does not work with Anti-aircraft Missile or similar weapons that have same projectile due to not firing warheads but instead cluster missiles. However the skill does work with Key of Reason due to firing auto-target warheads and not cluster missiles.
