As of currently, there is a major bug in game with Unsealed spellbook and hexflash. If you have hexflash and your flash is on cd, and you swap the flash spell for any other summoner spell, it will not be available DURING COMBAT. This is because hexflash goes on cooldown during combat, as it should, but the problem persists that my champion swapped to another summoner spell instead of hexflash.
Please save another blitzcrank/alistar's elo and spread the word. I was really wanting to test this new keystone out but I need my hexflash.
I went into testing in practice tool with a 100% reproduction rate, because of hexflash I could not use whatever summoner spell it was swapped with when I entered combat, but if I swapped my other summoner it was still available at all times. If my flash was up however, the bug did not occur.
