“As Achilles, heal 12 times in a single use of Radiant Glory.“
Radiant Glory is the second ability of Achilles.
In order to get a heal, you have to deal damage to enemies with your abilities while Radiant Glory is active. It is active for 6 seconds, and as well as this heal, you will gain bonus physical power, physical protections and crowd control reductions.
You get a single heal for damaging one enemy with your abilities, while Radiant Blessing is active. At the first rank of Radiant Blessing, you can have two heals maximum per ability. So, hit two or more enemies with one ability and you will get two heals. At max rank of Radiant Glory, you will get a maximum of 4. So in order to get this achievement, at Radiant Glory max rank, you will need to hit 4 enemies (gods or minions) 3 times in 6 seconds with any combination of your abilities.
Max out your Radiant Glory, but only put 1 point into each other ability, including your ult. Run up to a full wave of minions, activate your Radiant Glory. Hit them all with your 1st ability, activate your third and dash backwards then walk a few steps forward and strike forward up the line of minions (may need to hit the button you use for this ability again in order to strike), then use your ult to dash forward, straight through all the minions. This should get you all the heals you need. You can be at full health, and you do not need to hit any enemy gods.
In terms of items, you could build cooldown items such as Gladiators Shield, Breastplate of Valour and Jotunn's Wrath in order to reduce the time between uses of this ability and all others while the Radiant Glory blessing is active.
I suggest attempting this in Arena. Enemies group up quite a lot, and in Arena you can run around the buff monsters and sneak up on enemies if you're careful enough.
Massive thank you to
KBop a doo who has kindly recorded a video of her earning this achievement.
This video confirms that you
do not need to have lost any health and actually get healed by Radiant Glory, and that it work on all enemies including minions, not just gods.
I just earned this achievement myself yesterday, the exact way that KBop did.
