There are two phases of Souldrinker, the first is charging and the second is spitting it out.
Delta starts by spinning as fast as he can. While he is spinning his, spikes will withdraw for him to swallow. Because of that, his spike based attacks and his ability: Iron Barbs, won't work until the spikes restored. The spikes will restore after 2 rounds of the charging phase. While he has the souldrinking seed stored, his shell will glow a bit of light. The charging phase is done at the end of the move, being able to use the Spit Souldrinker for the next move.
Delta now finishes his move by bouncing into the air while spinning vertically, then he aims at the opponent and spits the shining green seed out of the top hole of his shell. If the seed hits the opponent it'll grow green vines with silver thorns out of it, which will wrap around the opponent. Then it'll act like a Leech Seed, however instead of draining any HP, it'll drain Energy. It will also restore a bit of Delta's energy for the energy drained off the opponent on each turn. The seed doesn't work if there is a Leech Seed already on the opponent. The spitting phase can be used whenever the trainer wants.
Charging Phase: 7%, Spitting Phase 10%.
-After charging it,
it doesn't have to be spit out for the next attack. He can store the seed and wait until the trainer commands him to. Also the spikes he withdraws causes him to not be able to use attacks which has to use his spikes. Also his Iron Barbs ability won't work. This effect will stay until two rounds after using it. The charging phase is done after Charge Souldrinker. That way he can immediately use Spit Souldrinker for his next move.
Moves that fall under the spike-less effect.
-After spitting it,
it will leave a Souldrinking seed on the target, which is basically the same as a Leech Seed, but it'll drain energy instead of HP. It also restores energy instead of HP. If there's a Leech Seed on it, the attack doesn't work and the seed will be wasted, the otherway around is the same, if the Souldrinking seed is planted on the target, Leech Seed will not work on the target.
One time to charge and one time to spit in the whole match.
