So, I’m pretty sure I might be the first one to actually obtain me. A few of things to note. Yes, I did spend a ridiculous number of runes to get her. How many, you ask? I have no idea. I wasn’t really counting anyway. The TapJoy offers helped, especially during the 1.5x rune weekends. Do I regret it? No. Is she worth it? IDK. For me personally, she is (for somewhat obvious reasons). For you, well, it’s up to you to decide, isn’t it?
Once you get to 1000 Trust Points, that slot turns into the unlocked Light Fury baby, and a new slot is taken, with the Trust Point meter starting at 0 plus whatever excess you got in that last fight. If you have any other questions about her, check the semi-“official” wiki at: https://dragons-titan-uprising.fandom.com/wiki/The_Light_Fury. If your answer cannot be found there, comment below.
