Q.英霊ポイント足りないんだけど! †
基本的にランクアップする事で英霊 イントが貰えます。
しかし、ランクが上がっていくにつ てランクアップが遅くなっていき、 霊ポイントの取得が遅くなってしま います。
目標とする最上位英霊を設定して上 くポイントを貯めましょう。
他にも下記のような取得方法がある で、余裕があればぜひ取りましょう
・Rankが1上がるごとに30P
・パネルミッション報酬30P×3回
・降臨戦でマテリアルと交換10P(最 30回)
・レイドイベントでの報酬
・ユニオンイベントでの報酬

Q. I don't have enough soul points to unlock heroes!
The main source of soul points is from rank increases.
But rank increases slow as you reach higher ranks, so the rate at which you'll acquire soul points will also diminish.
Determine which legendary spirit you want and use your points wisely on the prerequisite heroes.
Sources of soul points are listed below:
- Rank Up: 30P each
- Panel missions: 30P x 3
- Advent event turn-ins: 10P (max of 30x = 300P)
- Loot from Raid events
- Loot from Unison events
The general consensus is that snatch has a very small effect on drop rates that isn't noticeable, perhaps in the range of 1% per stack (e.g., a 1% drop rate on a rare item would increase to 1.05% with 5 stacks). A large-scale study would be necessary to demonstrate a statistically significant effect.
