Decided that if everyone else is doing it, I might as well exploit Shards too. Heh.
Field U4 Haunting - Maxed except Swarmlings(reason below).
1e15 / 999 Waves / 999 Monsters / 69.70 Multiplier / 35 Pool Multiplier Estimate / 2.41 Talisman Multiplier = ~170,000 XP per monster required.
Now, the reasoning. Even before the Freeze Debuff that Swarmling Domination brings, it already drastically reduces the base XP.
See - Base Endurance = Unknown % Norm/Swarm/Giant.
Giant Endurance = U*1.35 Giants. Giants give 50% more XP than normals, and assuming that the extra % of giant waves decreases the % of swarm & normal waves(duh), that bonus increases further.
So I estimate that having 35% more Giants and 0% more Swarms would give ~33%(0.33) * 0.35 * 150% = +17%.
Furthermore, 33% * 1.35 = 44.55% total giant waves. Reducing both Normal and Swarm by ~5.5%, yes?
swarms give 0.5x XP. 33% -5.5% = 27.5%. 33%/27.5% = +20% more XP from less swarm waves(I think).
Now, plug it into the above formula for XP/monster. If you change 69.70x to 78.10x, you need ~146,000 XP. If you divide 170,000 by 1.2 AND 1.17, you get... 121,000.
That's my reasoning anyway. Also, with the Freeze Debuff with that trait, that already counts for +10% extra xp/monster in my book for that much less risk and hassle. Therefore, that is why I refuse to play Swarmling Domination.
Messed up, restarted, it's going much better. I forgot about Cleansing Beacons earlier...blame my GC hiatus.
Anyway, I fought at least 6 shadows in the first 10 waves..was pretty difficult, with 100sec lock, had to use a G6 ampgem with beam to kill the first 2 shadows(wave 2 & wave 4).
IMO it's only increased in the first 10 waves IF you face multiple shadows and don't want to kill any monsters at the same time.With max Lock & Haste you gain mana every 6 waves, so it's a bit hard, yeah.
At least I had never more than 20 or 30k on screen! And 40.000.000 hits sounds much, but that is "only" hitlevel 30 - you should consider to farm more than 2 or 3.3 bn hits for hitlevel 38/39. Once the killgem is ready you don't get too many hits on it!
Over one trillion... Sorry, I don't think so! One trillion would be hitlevel 50 and as far as I know no one ever had so many hits... Even Borthel on his one-month-lasting run has "only" 300-something bn! bn=10^9 =1.000.000.000 trillion=10^12 = 1.000.000.000.000
