Drink all the unidentified potions in my possession and see what happens.
[3] Somehow, the potions have absolutely no effect. The combination manages to perfectly cancel itself out.
Oh god I struggle and try to get away from that statue and get out of the mud!
[4] Using the statue's shock at passing through the floor, you manage to escape it's grip, swimming back through the surface.
attempt to drain power from the enemy to boost my next action
[1+2] Something about the changing nature of the plane's magic inverts your spell, draining you instead of the enemy. You manage to cancel the effect before there is any significant draining though.
"WALDO!!!"
[2] Nope, still can't find him. Man, that guy blends in WELL.
In the hopes it will bisect Waldo's construct, open the earth plane to the lattice! "At high tide." The surge will be devoted to keeping displaced people alive by allowing each a space apart from space to step into until things settle down. Presumably...
[5] With yet another plane added to the spell, the half-solid ground beneath you suddenly changes to solid stone. Moments later water erupts from the ground, forming huge loops and arcs in the air before crashing back into the ground. currents of water flow through the air, all around the the plane's skies.
Absorb the mud, upgrading further from steam (fire,water and air) into a volcanic geyser cloud, balanced along the four natural elements.
[2] You fail to incorporate the mud into yourself. You also don't get yourself killed though, so that's a plus!
GIGA ICE BREAKER, DRILL INTO THE DEPTHS AND DESTROY THE STATUE!
[5] You drill into the newly formed solid ground! Unfortunately, you can't seem to find the statue anywhere in the stone where it was located.
