[Guide] Should you pull - B-Rank Idol Helena
https://dotgg.gg/brown-dust-2/costume-guide-b-rank-idol-helena/
This is a repost of the previous banner guide from the last banner 6 months ago. The recommendation remains the same!
TL;DR: When Helena was first launched, she was the best magic buffer in the game - but only because she was the only magic buffer in the game. Now that we have access to both MC.Teresse (5-star) and Elpis (4-star), Helena is still very strong in PVE, but no longer essential since there are other acceptable alternative options for magic buffers.
On the other hand, in PVP the opposite is true. At launch, B.Helena was just an "okay" buffer for 2 SP, but now with her potential upgrades, she's one of the best PVP costumes available. 50% crit rate and 115% M.ATK is no joke!
In some ways, I think B.Helena's evolution shows the care and attention from the devs in balancing the game. Rather than letting old costumes get powercreeped into irrelevance (like most other gacha devs), B.Helena remains very relevant, but now excels in different ways.
