Tyranid weapon-symbiots are usually conjoined to their bodies. To represent this their rate of fire and strength depend on the creature carrying them. A Tyranid that carries two of the same ranged weapon symbiote counts them as twin-linked.
Strength: Ranged bio-weapons have a Strength equal to the creature firing (S), modified as shown in the bio-weapons profiles below. The toxin sacs biomorph (+1 Strength) does increase the strength of ranged bioweapons carried by the creature. Bio-weapons are limited to a maximum strength as noted in their profile.
Rate of Fire: Many bioweapons are Assault X weapons. These get one shot per attack on the creature's basic profile (before being modified), so 2X weapons get twice the creature's attacks in shots, and so on.
