It is kind of like a mini-avatar fight, except you generally only have to use a 2hr bloodpact twice instead of 3 times, so in a way, it's easier.
Here's how my fight went. Upon arriving in the combat zone, I immediately ran up to Maat and gave him a /slap, just because he deserves it. I moved back a few steps, summoned Titan, guzzled a Yagudo Drink (didn't really even need it), used Astral Flow, commanded Titan to Assault Maat, and quickly used Titan's 2hr bloodpact. As soon as the BP went off, I ran down the ramp to the far end of the zone, used a Hi Elixir, and waited for Titan to die. As soon as he did, I summoned Shiva, and used Diamond Dust as soon as Maat was close. Maat was still alive and dragon-kicking at this point, so I started to run back toward the platform - but after a couple of melee hits from Shiva, Maat was down.
I've seen a few videos of the SMN Maat fight on YouTube that use this strategy, which is why I did it like this - except, unlike the videos, I didn't use any buffs, not even Earthen Ward.
