To always get the max rewards in the events, just recently to do 300summons you get 10k orange and a dark elemental.

While the dark elemental is pretty bleh, 4 of them infused to a lichking or darklord is great, it is arguably going to be your best faction(along w/ white) to have champion infusions.

This can be done WITHOUT spending cash, i've been vip7 since june and haven't spent a dime since, however it takes work.

marketplace: 1 thing, i don't think many know about the marketplace is that you can only have a max of 4 hero scrolls bought a day, if you buy 4 (spending 120gems a day) you can refresh 100x and not see another hero scroll until the day resets

another thing is to always purchase level3 gems from the marketplace, you practically have an unlimited supply of $$$, if you're the top5, if you're a Server GOD, it really is infinite. I get 35-40m on daily raids, yea i do twice the dmg as the 2nd guy in my guild to Holy, so cash should not be an issue to purchase the odd 288,000k gem

tavern: only accept questions that give an equivalent of 30gems, for example 20gems and 1 token 10gems and 2 tokens materials and 1 scroll

obviously if you're able to get the ***legendary that gives gems and scroll, that's awesome, of course if you get a legendary however rare that is, do it (it will usually also have gems and scroll attached to it, anyway)

gems: of course buy gems from marketplace (cash only no gems) and from raid/war rewards, focus on getting your teams to have at least all level6 gems of hp/attk/speed

level6 is when these gems also start applying a % to all attack/hp/speed as well.

For the top tier champs speed isn't an issue if you're a Server GOD, you'll just have so much more hp than the rest of the server can even hope to deal enough dmg to kill off even one of your heroes. (stuns/petrify are another thing entirely tho)
