(PF) Dr7, max grapple?

[Occasional Sage]

As the title: if you can Wild Shape as a seventh-level Druid, what form maximizes your CMB for Grappling?

ETA: +19 is the number to beat. Creature must breath air.

[Necromancy]

Best you can do is dire bear

1 CMD/CMB for size
2 CMB/1 CMD of stats
4 CMB for having the grab ability

So total 7 bonus CMB and 5 BAB IS 12, plus base str modifier

[Psyren]

The grab ability also means you specifically use your natural attacks/unarmed strikes to perform the grapple. This means any enhancement bonus to those weapons will count towards your CMB, e.g. magic fang or amulet of mighty fists.
