1. All boost can be dropped as a item with a rarity between barriers and recon/artillery
2. Just like barriers they come in:
-standard ☆☆☆☆☆ 2 second tier 1
-super ★★★☆☆ 5 second tier 2
-ultra ★★★★☆ 10 second tier 3
3. Add weapons (sword, bomb, gun variants) that have a medium chance to give boosts (the better the boost the rarer it will be given) to the user and other party members when using it's charge to attack
Please tell me what you think, before I go into more details.
We have enough boosts already.
