Just an idea for 2 skills.
First one is the glue shot skill.
Has the same effect, but just slightly changes its name and animations.
● Cluster Shot
Shoots a bullet that explodes on impact, and scatters mini caltdrops around the area.
Instead of the glue, we see shinny caltdrops after a small explosion.
Also for refraction cutter.
● Sonic Cutter or Sonic Slasher
Instead of the yellow projectile, could be a blue sonic slashing projectile; to match the other skills.
Fuse equiped sword with handgun.
Becomes a two handed weapon in which serves as a sword and once the holomode reaches max heat, it gives you a special skill that intensifies damage with critical hits.
