I never thought about mutation shield and poison shield buffs becoming boosters... I guess you could try also adding it in (but at the cost of disabling the buff effect entirely when this booster is active)

Here's how I'd think about it

Mutation Immunity Booster
Description: Gives you x% chance to resist being Mutated by infected attacks and tank abilities. It also powers up your resistance to health decay while Mutated for 10 minutes.
<Can stack with other status immunity boosters>
<Disables |Q| Mutation Shield while active>
<X VS>

1st Grade: Would require 1x Mutation Refiner
2nd Grade: Would require 2x Mutation Refiner
3rd Grade: Would require 5x Mutation Refiner
4th Grade: Would require 10x Mutation Refiner and 1x Volatile Tank Blood

As for the Statistics:
1st Grade: 10% chance and resistance
2nd Grade: 15% chance and resistance
3rd Grade: 20% chance and resistance
4th Grade: 25% chance and resistance

Poison Immunity Booster
Description: Gives you x% chance to resist being Poisoned by infected attacks and tank abilities. It also powers up your recovery rate from incaps while affected Poison Bad Status Effect for 10 minutes.
<Can stack with other status immunity boosters>
<Disables |Q| Poison Shield while active>
<X VS>

1st Grade: Would require 1x Poisonous Gland
2nd Grade: Would require 2x Poisonous Gland
3rd Grade: Would require 5x Poisonous Gland
4th Grade: Would require 10x Poisonous Gland

As for the Statistics:
1st Grade: 10% chance and 5% recovery rate
2nd Grade: 20% chance and 10% recovery rate
3rd Grade: 35% chance and 15% recovery rate
4th Grade: 50% chance and 20% recovery rate

Iron Immunity Booster
Description: Gives you x% chance to resist becoming Knockbacked/Staggered by infected attacks and tank abilities. It also increases your recovery rate to Knockbacks/Staggers for 10 minutes.
<Can stack with other status immunity boosters>
<Disables reduced/nullifying knockback effects from buffs while active>
<X VS>

1st Grade: Would require 1x Charger Blood
2nd Grade: Would require 2x Charger Blood
3rd Grade: Would require 5x Charger Blood
4th Grade: Would require 10x Charger Blood

As for the Statistics:
1st Grade: 5% chance and recovery rate
2nd Grade: 10% chance and recovery rate
3rd Grade: 15% chance and recovery rate
4th Grade: 20% chance and recovery rate
