Please help me optimize a solo setup spikegrowth grappler. Spike growth into brown bear wildshape and unarmed strike into grapple, using new grappler feat to drag enemies through spikes at full speed.

Wondering if multiclassing into monk would be good for movement bonuses and bonus action grapple attempts, or rogue for movement and bonus action chains for added control and heat metal if I lose wildshape, or something else for con saves to maintain concentration.

All thoughts welcome.

Thanks.
