Theresa is only available by AstralOP supply.

You're guaranteed one Serapeum every 60 pulls.

She gets her first supply in 7.6, opening on February 20th and ends on April 4th.

I only did 110 pulls for SS, I'm basically lucky... haha... (help)

✦ Rank-ups ✦

✧ Analysis ✧

S Rank

Unlike other AstralOPs Teri is already an amazing upgrade for Law of Ascension without an rank-ups. The Initial Intensity and DMG are the key buffs for Law of Ascension as the characters of the specialisation already have good Intensity regeneration by themselves.

SS Rank

This is the minimum needed to be good for Vita and it's a nice buff for Law of Ascension as well.

SSS Rank

SSS is a pretty nice DMG buff for both specialisations. Can take it if you can, don't need to.

Overall

All Rank-ups are pretty good, so the decision mostly depends on your budget and account on how much to go for. If you wanna use her for Vita SS is recommended.

✦ Conclusion ✦

Is Theresa a good pull?

If you have a good Law of Ascension or Vita team and wanna upgrade it she definitely is!

Please note she needs at least SS to be used in Vita teams. Pulling her for if you have SS+ Songque generally isn't worth it because the upgrade isn't that big.

However, she is the first AstralOP to have all the important stuff for her own Specialisation in her S rank. Considering Law of Ascension already is a great Specialisation for F2Ps because they're not as dependent on a good AstralOP she could be the last upgrade for F2Ps who wanna build a strong Part 2 team.
