I ran a funky Rt/R spike build with SS a little while ago. Just fancied a change to the usual splinter barrage or SS para builds i'd been running. Vanquished quite a few areas with it and it's great for sniping targets, especially monks.
It's a bit slow to set up the spike but i nearly fell outta my chair when an enemy in HM went from 80% hp to zero in under a second.
It was:
Triple Shot (rank doesn't matter)
Distracting Shot or Needling Shot (depends if you want more damage or an interrupt)
Asuran Scan
Read the Wind/Rapid Fire
"I Am The Strongest!"
Vital Weapon
Sight Beyond Sight
Spirit's Strength [E]
Attributes:
Spawning Power - 11+1+3 (you have Vital Weapon so you can afford the Sup rune)
Marksmanship - 11
Communing - 8
Basically you cast everything from Spirit's Strength to Read the Wind/Rapid Fire either just before you aggro or while someone else is aggroing for you. When your target gets in range you cast Asuran Scan on them and wack em with Triple Shot and D-Shot/Needling shot. With RtW Triple shot will do 350+ damage to a 100AL target, D-Shot does 89 dmg, Needling does 143 with the ranks i have in the EotN titles (r9 asuran, r7 norn). Needling shot is especially effective at taking down target very fast indeed. An initial spike of well over 300 with follow up shots every second of 143 really hurts. It takes the 100AL dummy down in 4 shots every time (triple+needling). That's a spike of at least 480 vs 100AL in about 1 second. Even regular hits with no asuran scan hit 100AL for 75-95 and with asuran scan only, 125-150.
Asuran Scan really is God mode with SS builds as Dr Strangelove said. It not only increases base damage but all bonus damage aswell. SS normally does +35 but with AS it does +58 (with asura rank 9). "I Am The Strongest!" normally does +17, with AS it does +28 (with norn rank 7). RtW does +8, with AS it does +13.
It's great for gits and shiggles
One thing though, it is quite energy intensive so you will need around the 40-50 energy mark to use it effectively if you don't want to wait for regen between spikes.
I had great fun with it once i learned to use it properly. The key is to set up your spike
before the fighting starts and take down key targets like monks or eles first. Killing a HM Jotun Skullsmasher in 3-4 secs is easily doable. Think of it like a ranged version of an Assassin on steroids.
Another thing i just remembered. If you can target something in the middle of a group and have a nec place Mark Of Pain on them you can do some serious AoE damage aswell with Triple Shot and Needling Shot hitting so fast.
