As the title suggests lol i have a low shield atm on my defiant a mk 4 4800 shield but i am unsure as to the best shield for a mobius ship, any help

Get the Aegis set that will last you well into VA.

I will tell you what I always tell people.

Forget doing anything until you level 50. Until that time it's doff and mirror event.

Im gonna do the omega marks at level 44 but want to have a decent shield, is regenerative decent for an escort or is resillient better?

Jem'Hadar set. Free, its a pretty solid set in its own right, and even at Mk10 its solid enough to last until you're picking out your endgame gear.

Where do i getvthe jem hadar set? Im on season 2 atm and heard im not far from getting a reman shield

The Reman shield is decent, good cap but low regeneration rate and no hardening. The Jem'Hadar set is from the Dominion featured episodes near the end of the Cardassian arc, so you'd have to skip ahead or just wait to play another 20 missions. The engine and deflector are both from the mission "Operation Gamma," and the shield is from "Boldly They Rode." Might be worth the jump ahead and do the whole Dominion series (its one of the better arcs IMHO), starting with "Second Wave," then go back and do the skipped missions properly.

The reason the Jem'hadar shield in particular is nice is that it gives 10% reduction to all damage period (including kinetic) plus a crew survival bonus, and its a Resilient shield and so reduces bleedthrough. Even has a decent cap and regen rate besides. Additionally, the 2-piece set bonus gives extra damage to polaron weapons, and the 3-piece gives you an extra cloak detection and AOE-shield zapper (not that powerful, but a little extra damage never hurt). Probably the best gear around short of the Reputation and Fleet based stuff.

Actually.... if you grind the story missions until you get to the Dominion FEs, you'll probably get to level 50 before you pick up the shield.

If i skip to the dominion bit will they be near my level or is it best to wait? The dominion kit sounds gd but i think the reman shield will hold me for the mo, when do i start finding polaron weapons? Atm im using tetryon heavy cannons and on the back quantum mines and a tetryon phaser

They'll match your level, whatever that is. the rewards will match your level too. You can repeat the last mission in the Dominion series to get Polaron weapons.
