You can always save up and buy from AH (Pulsars are like 30k or something the last time I checked).
But Quicksilver also has that little walk speed boost that may help you outrun players who are either not striker or a striker without boost (I never used it so I don't know if the walk speed increase makes any difference).
T2 LD Bomber gear- is quicksilver mail worth using over brute jelly?
Put the extra effort in for the Quicksilver. I wouldn't bother with the Supernova just yet, tbh.
It'll be worth it when you get past the Lightning Capacitor/Kilowatt Pulsar spam to lodge a sword in the face.
Edit: Walk speed bonus does make a difference, but that only comes into play with the 5* versions.
Well Owao, brute jelly works quite well in standing up to toothpicks, Antiguas, and various other stun and pierce based weapons.
But Quicksilver defends against pierce just as well, and has a resist to the bomber's bane, shock.
You'll do fine with brute jelly, but the shock resist will help in a lot more situations since stun doesn't affect bomb charge times at all.
~Qaz, the crazy shard spammer
Quicksilver has everything a bomber needs and has the same piercing resistence as the brute, along with shock.
The only quirk is the long time to get the tokens, but it shouldn't be too hard now that they put in the missions.
~Rank, the Noob in LD
The primary reason to get Quicksilver over Brute is to deal with Kilowatt Pulsar. I never found KP to be much of a problem, but you certainly have nothing to lose by getting Quicksilver. You almost never get stunned in T2 LD.
If you're a bomber, protecting yourself from ever getting in melee combat is the first thing you should learn, followed by dodging close range pulsar shots. Quicksilver is better for both of those.
If you really want to compound those problems together while searching for the better ld set, going to have to say jelly.
But, comparing the two, quicksilver is just much better. Existing in every game, so does the timeless mantra of grindingforbettergear appear here.
Effort=good gear
Noeffort=less than good gear
