Quills

Hundreds of needle-pointed quills cover your body.

(level based) quills
May expel 10% of your quills in a burst around yourself (→(level based) 1d3)
Regenerate quills at the approximate rate of (level based) per round
+(level based) AV as long as you retain half your quills ((level based) AV otherwise)
Creatures attacking you in melee may impale themselves on your quills, breaking roughly 1% of them and reflecting 3% damage per quill broken.
Cannot wear body armor
Immune to other creatures' quills

Quills is a physical mutation that grants the quills natural equipment, providing the player with natural body armor, melee damage reflection, and the ability to discharge their quills to deal damage around themselves. The total amount of quills the player possesses, how quickly those quills regenerate, their penetration value, and the AV bonus provided by the quills are determined by the mutation level.

Each time a creature gains a mutation level in Quills, they receive a random bonus to their maximum quills between 80-120.

Formulas

The following formulas are used to determine quill penetration, quill regeneration rate, the AV bonus for having ≥50% quills, and the AV penalty for having <50% quills, based on mutation level. For the AV Bonus, integers are rounded down, and for the AV penalty, integers are rounded up. Note that the formula for the AV bonus only applies if the mutation level exceeds 3; otherwise, the bonus is 2. Additionally, quill penetration cannot exceed →6.

Quill Penetration	(Level - 1) / 2
Base Quill Regeneration Rate	Level * 0.25
AV Bonus (≥50% Quills)	(Level / 3) + 2
AV Penalty (<50% Quills)	(AV Bonus / 2)

Advantages & Disadvantages

This section is opinion-based. Your mileage may vary.

Advantages

• Quills provide a moderate AV (as long as the player retains at least half of their quills) which scales with mutation level while also having no DV penalty or weight
• Quill burst hits all adjacent tiles
• Reflects melee damage
• Makes the player immune to other creature’s quills
• Hits flying creatures

Disadvantages

• High cost at character regeneration
• Quill burst has fairly poor damage that cannot be increased by mutation level, and penetration caps at →6
• Quills prevents the player from wearing any body Armor
• Quills lacks elemental resistance that normal high tier body armor provides
