You did well Relic, but you won't last too much longer. Still, let's see if we can draw this out for one more round.If we can just outlast him..

You can't dodge it, but you can still Protect! Hopefully, it won't wear you out, as it's weakened down here.

Next, let's use the environment. Use a Quick Attack to dodge behind the pillars created from Rock Tomb. Those flames are powerful, but they can't pass through solid rock. If for some reason the rocks cannot be used for cover, Endure the hit instead.

Finally, all of your moves are physical, so we have no choice. Step out from behind the rock barrier, and release a Hyper Beam at full power. I'm not sure how you're going to ref this, Elec, since a "stream of liquid, gas, or energy" is considered a special attack according to the beta attack list. It's really up to you. Either way, I'm counting on the strain of the attack over actual damage.
