Didn't see one yet, so figured I'd put this together. Please help fill in the blanks if you can. Dreading the kill counts for Days 5-7, given how low it started this time.
Also, another thing to note is the high gold cost for anyone trying to climb this time around. It's now Boss Level multiplied by X, where X is based on your level. The only data I have is the following:
Lv 89 - Lv x 200 gold (Lv 100 per gold hit = 20,000)
Lv 139 - Lv x 400 gold (Lv 100 per gold hit = 40,000)
Lv 200 - Lv x 500 gold (Lv 100 per gold hit = 50,000)
WARNING - XP gain is high, on both kills and quest-based. For kills, the formula appears to be (BossLv * 5) + 5. (25,750 XP gain just from kills for 100 levels) Even LLPs have reported that the gain is absurdly high. One player leveled from 49 to 57 in ~55 bosses. The quest XP rewards are also severely high, apparently based on your level/tier, and not what's truly shown. Once again, seriously consider if it's worth killing more than what your guild needs.
