I beat him with Naga Sadow in sealed. Sith Sorcery to burn his Force points, and possibly activate him, and then poison damage ftw.

We had a GMLS face-off once. It was totally ridiculous, because the chain djem so-ing gets so complicated that you have to draw a flowchart just to keep track of how many attacks have actually happened. It basically guarantees that both die too unless one person refuses to use djem so at all, and that's kind of silly because you end up taking 50 damage to do 20. A similar situation actually arose during the Owensboro regional, except it was GMLS and Vader Scourge. I had already finished my game so I went over and started drawing the flowchart for them, hahaha. Unfortunately for Vader he failed too many djem rolls and ate it; normally I like his chances at 40 damage a hit.

1. Djem So guys are best able to keep the damage up, though they are quite likely to die, but sacrificing a 46-55 pt piece for double that, is okay.
2. High damage single attacks. Boris's example is perfect. It really limits the damage from Djem So Mastery. Good examples are Naga Sadow and Darth Bane.
3. Parry/Makashi Mastery is able to tie him up decently.
4. Throw/Direct damage. Bypass Djem So completely. Run the risk of Force Defense though.

God, I love the Djem So Ping-Pong rallies. One time my friend and I went at it with two GMLS's in 150; it took us literally ten minutes to resolve one attack phase and maybe a total of forty Djem So and LS Defense saves (we were running Leias). That was the single most confusing time I've ever had in SWM.

Well IMO & the only way i know how to stop GMLS is basically his force powers are what makes his hard...

Lord Vader i say would be the best melee straight up to hit him. Use thrawn So you can swap in & base him, make sure he can only force defense once, cuz then you can LSA, when he force defences then you basically use overwhelming force on him with opp from thrawn, so ur doing 60 dam w/ twin or if he is really low on fp's & his force defense will make his run low, then basically LSA first,let his force fense, then basically sith rage & get 40 dam out w/ opp a pop..u can keep repeating these processes & he is down in no time...or then ur shooters should be able to take him down..

Or u can have nomi,lobot & exile on a team, wait till low on fps & he acts, then base him with nomi, make sure u have lobot to get recon & make sure exile is within 6 of GMLS, then u go to sever force if u win init help from lobot & recon, he'll force defense then w/ he exile u force defense back & he's out of force, then u can get him with range & shooters & actually use nomi & exile to attack him as well, only 2 ways i know how to beat GMLS cuz i did these 2 ways both times & it worked..

Never had to face GMLS yet in a battle (surprise!)...but I have used him a few times and I can't recall a time when he's died on me

Old school thrawn right? Force bubble on GMLS is hilarious! Vader scourge doubles with Jedi hunter and Luke can't survive...cause you've got initiative baby!

Sure have, with 4 different squads.

1 - It took 3 Vong JHs (only 2 died) about 2.5 rounds to kill him. Was an easy game, but you can probably understand why (no block).

2. Vader Scourge - Extremely easy as well. The odds actually favor Scourge in the battle (by a decent margin) with Opportunist, although it's possible they both die. Think of it this way. Scourge if swapped in with Opp has 3 attacks automatically, without djem so being considered (double, repost). If Luke wastes fps on defense of the repost, that's a win anyways. 3 attacks that do 40dmg per (120/150hps). Luke actually needs 3 Djem SO Mastery twins to kill Vader (which means he's lost 120hps unless he blocked one). Further, each time Luke hits Vader, Vader gets djem so for another 40dmg hit. And considering the dmg trade is 40 - 30 - 40 - 20 - 40 - 30 - 40 - 20 and so on, you can pretty easily figure who comes out on top.

3. GM Yoda - Was simple as well. Used my shooting support to widdle down Luke, used Luke to set up ASM throw on other opponent pieces (R2 became bait), once Luke was at 60HPs Yoda used double twin for the kill. Yoda survived actually (although it was hardly needed).

4 - Exile. Atton Rand and Dash smoked Luke early and often, and the Exile had little trouble taking the last 40hps off (she took like 20 earlier off of Luke).

He doesn't have an attack period. Lord Vader is the worst option.

If that is indeed the question, then it's the most pointless question one could ask. Luke is 115pts. Why on earth would it matter if a single character who costs 1/2 or less of his cost has taken him down in a one on one match up, particularly a melee character, which is what Luke is designed to kill? The game is played by squads. If this isn't a squad related question, then it isn't related to the game.

And further, his example of the time he did it was "a beefed up Lucien Dray". I'm pretty sure that was meant to include other components to squad building, not some made up one on one format of trying to beat 115 point piece with a 50pter.

If you read my examples, all of them started with Luke at full health. He can be beaten with melee pieces, the ones I gave were all direct examples of who I've used. Your best tactic isn't always to run right up to a full health Luke and start taking melee attacks. But you also don't do what so many people have said on the topic either, and never attack him with melee. It's all about timing, understanding the damage exchange and the odds. You play them right, and melee characters do just fine taking down Luke.

In the case of GMY for example - I was well aware that I could count on my Yoda to remove 60dmg from Luke (took out his support first including his Leia). However, instead of going right for it, I chose to keep Yoda alive, giving out his CE, presenting Luke with bait, and for force defense for an extra round. That made the difference between winning easily, and risking a 50/50 loss. Keeping Yoda alive, meant that I could defense a LS Defense on a 30dmg shot (defensed the reroll), kept 2 of my shooters at +3 attack, and that I could finish the game once I got Luke to 60.

Whether or not the OP intended that kind of answer, these are the ones that I believe are most helpful to other players, so I post it whether that person is looking for something else or not.
