Luke Skywalker journey

How "well above" are you?

You are talking about the Commander Luke Hero's Journey?

Funny thing about this game is that those numbers indicating power are the worst way of thinking about your toons. Lot of tiers requires specific tactic, specific mods. Tell us what tier of what journey exactly you are having trouble with and show us your modding otherwise we have no chance to  tell you how to improve

Specific Omegas and Zetas are incredibly useful for that event. Farmboy's Bullseye ability, for instance, should be Omega'd. It's very hard to crit in this event, but that's not a bad thing since with the Omega you dispel buffs when you don't crit using Bullseye. 

So if you have the Omega, you can wait until someone taunts, then dispel it using Farmboy, and that allows you to focus damage on the enemy attackers. That strategy is important on at least 2 tiers, though I played the event so long ago I don't remember which ones. (Replaying it now would be useless, all my toons are relic and would one-shot enemies so I wouldn't have a chance to try different strategies.)

Meanwhile the STHan zeta is important for protection recovery, allowing you to survive much longer than otherwise. If you can mod him for Protection and Potency, that also helps. 

Princess Leia needs an Omega on her special Rebel Tactics so that she can stay under stealth 100% of the time. The zeta on Against All Odds is very useful if you can afford it, but it's not necessary and if you're going after CLS then you have much more important uses for those zeta mats, so I wouldn't spend it on Leia. 

What MasterSeedy said above is true, but I would NOT put the zeta on Stormtrooper Han yet. That's kind of a luxury zeta and won't make much difference until he's higher gear/relic. You'll need the zetas for much more important characters—especially Commander Luke Skywalker. With good mods, the event should be very doable without StHan's zeta.

It’s 100% doable without STH zeta and STH has a LST coming February 24th so it’s kind of a waste to apply it.  Leia and Farmer Luke also on February 10th.  I can’t remember who else is needed for that event but in that grouping of LSTs you also get Old Ben, Ackbar and the token that upgrades CLS if you have him unlocked.  It’s probably worth your while to hold off on CLS until you get those tokens, just my opinion though.  Good luck!

My power is 21,717. After reading all the reply I have realized that my gear tier isn't High Enough before the Luke Skywalker Journey. It's not me commanders Skywalker in Journey it is I guess they're very first one where you just have Han Solo and the Farm Boy Luke Skywalker
