For 100 Gems I decided to get the Flasks and use them to get a good sense of game play and how I feel about it first time out. First loss was on F24 and already have about 4 - 5 heroes cursed out.
I thought to myself, “Hey, I’m 8024!” then looked at the rewards. I like the 25 'blems of each kind but kinda underwhelmed. And at that ranking, I’m in one of the middle reward tiers.
Unlike the Challenge Events where you can infinitely replay for the best score possible, WE allowing, this one seems to be about bringing a ton Battle Items and blasting through them like there’s no tomorrow to get the best scores.
I tend not to use Battle Items much since all this grinding to get Buildings to 25 has really hampered my iron to make them and am only now starting to seriously restock.
After all this, I’m still wait and see how it goes after about 3 of them to really make up my mind whether it’ll be worth throwing tons of battle items into.
