This powerful technique is one of the secret techniques of the Beastman style. The user's animal companion doubles in size, and its weight is multiplied by 8 times. The animal companion gains one size category, which grants it a +8 size bonus to Strength and +4 size bonus to HP, as well as a -2 size penalty to Dexterity.

The companion also gains a damage reduction 5/chakra and a +2 resistance bonus to
saving throws. If insufficient room is available to allow its growth, the companion grows
to the maximum possible size and may make a Strength check (using its increased
Strength) to burst any enclosures in the process. If it fails, it is constrained without harm by the materials enclosing it— the technique cannot be used to crush the companion by increasing its size.

After this technique is used, the companion will be fatigued for the rest of the encounter. The companion cannot benefit from this technique while fatigued, and the effects will fail.
