Dude what the heck is going on in your signature? Been wondering this for a few days haha
Anyway Rebel cannot equip valk gear or the temporal dex boot, just tested this to be sure...a cheap alternative to e variant is vidar's boots, sadly, or regular non-transformed temporal boot upgraded, since this can be equipped by all job.
I know Vidar boot kinda sucks but its the best option for hp sp pool besides e variant+9 firelock, vidar, or normal temporal boot. Too bad silverleather is 160 only and can only use it at max level, its like the perfect rebel boot (well temporal dex EA enchant is better but we dont get to use it sadly)
Also for armor glittering jacket with dex+3 and dame of sentinel card is my personal favorite armor for rebel, it's not terribly expensive to make yourself if you're somewhat lucky with the enchant armor guy and dame cards aren't that expensive, with a puny 75 vit I get +7 dex from this armor alone, very handy. Zerom carded accessories give a cheap +6 dex boost as well, so there's that to consider. Dex seems to boost RT damage quite a bit so it's worth it to me to focus on the dex boost you can get from anywhere.
Dont forget you can get an e. variant for the low price of regular variant shoes if you have the time and patience to do 30 high energy crystal quests with one char, which is really tedious but I think it's worth it, even un-upgraded e variant is better than vidar's, but in 30 days you'll probably be 160 anyway so it won't matter at that point/
