It is worth noting (and saving up tokens) that the Tower Summon is more advantageous then the ordinary Epic one – the 10 % chance of gaining an ordinary Epic Troop is kept and the extra 5% of the special Tower ones comes at the expense of the baseline 90 % Rare. Troops can be gained as battle reward (1 and 2 star only) or summoned in the Daily Summon (which produces Heroes twice often than Troops, so the table lists raw percentage as well as the ratio of summoned troops), Epic Troop Summon (for tokens, 200 Gems or ) or Tower Troop Summon which replaces the latter during the Tower Events.
