Pespective: My alliance is killing 11* Titans and killing some 12* Titans. I’m F2P and have been for almost a year. I have 2 maxed 5*, 17 maxed 4*. I use Wilbur & Wu on almost every Titan hit. I complete events and only compete for some of the lower tier rewards if I happen to have excess items which I don’t primarily use on Titan hits.
Levelling Heroes/Training Centers
Super Mana Potion (until I run out of Meteor Fragments)
Minor Mana Potion (until I run out of mats)
Mana Potion (until I run out of Grimoire Dust)
Antidotes/Super (only if I’m low on antidotes, and normal vs super depending on which mats I need less)
Revives/Health Pots (never crafted)
Tornadoes (until I run out of any mats, most people would say nuggets, but I wasted a bunch of Iron on Arrows many months back and have yet to catch up)
Time Stops (until I run out of Dragon Bones)
After this I don’t really care.
Not Dragon Attacks because they use Dragon Bones and I’d rather use them for Super Mana. 1k damage is nothing vs a hero’s special.
Dragon Banners, Bear Banners, Bombs and Axes all use Ore so that’s usually the next limiter.
After that it’s Turtle Banners.
I don’t build Arrows since that Crude Iron could be used for Tornadoes. Might not be the most efficient since you can get 4 arrows per 1 Tornado.
All of that being said, this priority setup is for my situation. Primarily almost no 5* which limits my survivability a little. Also I’m trying to maximize my damage to maximize my Loot Tier and make it possible to kill 12* Titans and account for some of the weaker attackers in our alliance. I just did 7% of the 11* Titan damage(higher than average) where there were 4 members who did under 1% and 18 who did under 3.3%. I imagine if you’re in a top 20 alliance like Dator the pressure to maximize damage is lower and you’re just expected to do your 3.3% damage and not much more so that you can maximize the number of members that get Tier B loot. I did 3.3% damage with 3 flags (using tornadoes, 2 different mana pots and antidotes) I’d imagine I could do my 3.3% with 6 flags with the items Dator suggested.
Just to be clear there’s no judgement being made, just making sure it’s clear that there are different situations that need to be considered and there is no one size fits all strategy for battle item material usage. Thanks for the putting the effort into this conversation. I’m surprised it’s taken so long for this information to be consolidated somewhere.
