Commander (Deadly) is the final stage in Duel at the Lava Fields.
Cat Deploy Limit: 1
- Youcan spawns as the first wave.
- R. Ost spawns as the second wave.
- H. Nah spawns as the last wave.
- Assassin Bear spawns after 15 minutes.
Do not bother with this stage unless you have all anti-starred alien treasures.
Bring defensive combos, A. Bahamut and something to kill Youcan, as well as the Thunderbolt Cannon. Kill Youcan, then let R.Ost spawn and reach your base. Do not let him reach it too fast, as you'll need the cannon, so also use something to slow down R.Ost in case of need. Let him hit your base for a second and use the thunderbolt cannon or time Bahamut well to kill the R.Ost. Based on timing, Bahamut's level and R.Ost's luck with crits, Bahamut may win and proceed to cripple or kill H.Nah, at which point you may need to let Bahamut destroy the base or summon something like Bullet Train to finish off H.Nah. If Bahamut loses, use something like Vendor to gain time and distance on R.Ost, then damage him further as he comes back and repeat, then do the same thing for H.Nah, possibly involving another Bahamut.
