@Pipinghot Well, this is the exact same mechanic used when you force-feed narcotics; it DOES stacks. But since you wants proofs, I made a short clip for you better than a wall of text. Basically a Giga level 1 has 10,000 torpor. Since a single Tranq Arrow with a Primitive Crossbow deals 157.5 total, it will requires 64 arrows (10k / 157.5 = 63.49 = 64). Even tho, technically, it would only requires 63 because ((10,000 / 100) * 99) / 157.5 = 62.86 = 63 but I always go for 100% torpor. But anyways
