The Armored Giant Strider is the new legendary mount that will arrive with the Eternal Flame lockbox. (This is not the final release according to the devs, so this mount might change visually or even in his mechanics once its get released)
This is a very special mount because is the first one with movement speed above 110% since it’s coming with 140%. That’s not all, this is also the first mount that is “usable” during combat. It does a fixed damage on your enemies, afterwards, it will go cooldown for 60s. If you leave combat you will be able to summon it again.
If that’s not enough, it also gives to the character a 4.000 stat bonus to your character, we are talking about extra 10% mov speed.
In my personal opinion, I’m highly expecting for a Mount book IV to be released so we can upgrade our previous mounts to Rank 4 as well. Maybe not every mount is going to be able to attack but the bonus speed either riding or for our character are very interesting.
