Yep Yep. Most people get this contract for the Sage Mode and its boost to taijutsu.
We'll begin with the Enma summoning as he's the only one shown in the series. He specializes in Taijutsu, allowing his raw strength to play equal to Chakra Enhanced Strength. This means that his physical attacks gain +25. He also moves at the speed of a Sage ranked taijutsu master. Translated to the current RP I believe that's 11 (+2) to his base speed. He also doesn't take damage from C rank and below Ninjutsu or Taijutsu attacks. Then there's his ability to transform into a staff that can extend and similar to Goku's pole thing.

Type: Summoning
Rank: S
Range: Short
Chakra: 40
Damage: N/A
Description: A long-time companion of Hiruzen Sarutobi, suggesting that he too is rather old. As a summoning, he acts as not only a battle partner, but also as adviser—by virtue of his being a veteran with evident battle skills. His principal ability is hand-to-hand fighting, and his prowess is such that he is capable of using known Taijutsu, up to and including S-rank. In addition, his raw strength is similar to those whom use chakra enhanced strength. Beyond raw power, his speed is identical to that of Sage-rank Taijutsu masters. His old age belies high durability; he takes no damage from Ninjutsu or Taijutsu attacks, C-rank and below. And finally, he is able to transform into a nigh-indestructible staff, which has an at-will ability to extend and/or expand.
Note: Is only summonable once per event.
