Sei-mon Kai (Life Gate Release)
Hachimon Tonkou (Sei-mon)
Rank: 6 (B-Class);
Same as Kai-mon Kai except as noted above and as follow. The user opens the third gate. For the duration of the technique, he gains a +20 to Strength, Dexterity, and Speed scores. His effective Chakra Signature when sensing Chakra increases by +1, and he gains a +80 bonus to Chakra Pool.
Every consecutive use of any Gate-release Hachimon Tonkou technique within a 24 hours period reduces the bonus Chakra granted by opening a Gate by 40 (excluding Seishun no Chikara!!!).
Each round the technique is maintained, the user suffers 1d4+1 points of damage. When the technique ends, he must succeed a Fortitude save (DC 20) or be fatigued for the rest of the encounter plus 5 minutes.
The user can only perform this technique while under the effects of Kyu-mon Kai or with
sufficient degree of mastery in it.
Mastery
With the second step of mastery in this technique, the user can activate this gate as a free action for the purpose of using a more powerful gate, without actually performing this technique or gaining any of its benefits or penalties. He cannot otherwise perform the technique as a free action.
