Xenosaga Episode 1 (2002) - Elsa - Domo Carrier boss battle This is the first really difficult boss of the game and lots of it just comes down to random luck. IMO this battle was terribly designed and the game gives you no direction in what to do. It's very possible to level grind for hours only to throw away your T. Points into stuff that won't help at all for this battle. On the first turn Domo Carrier's main attack will be randomly locked into 1 of 4 Event Slots. If it gets locked into 2 certain ones, he will do enough dmg to leave your party at critical HP every time he uses the attack. Second, if the turns don't somehow get out of order before one of your characters has a boost built up, he will use the attack on every turn. The battle will be nearly impossible if 1 of those 2 things happen and your party WILL be wiped if both happen. As you can see I used Shion, KOS-MOS, and Chaos. Put Chaos into his A.G.W.S and alternate between guard and W-Act. Have KOS-MOS attack on every turn and have Shion heal when needed. If you know his powerful attack is going to come up on his next turn, have your current character boost KOS-MOS before it happens to get his turns out of order. Thanks for watching!
