Fairytale Tenebria

Stats and Sets

Building a control mage is relatively simple, just worry about eff%, speed, and bulk.

For playing F Tenebria as an initiator, simply max out her speed while still preserving eff%.

As a follow up control mage where she doesn't need to initiate, maintain enough speed to follow up the initiator and maximize eff% to guarantee the redirected provoke on their enemy soul weavers. In the current meta, while she certainly can be an initiator, she is much more reliable as a follow up as Cerise is the premier initiator and enemy immunities can be protected by a Fallen Cecilia as F Tenebria can only dispel 1 buff.

Speed set is basically mandatory to play her PvP while hit set is easier to farm and can help her become a better follow up controller.

Skill-ups

As she is a control mage, we only want -1 cooldown and + effect chance from her, which gives her a very budget +3 on s3 and a choice for players to upgrade S1 for consistency or skip entirely for molagora budget. She'll still do her job regardless.

Artifacts

Iela Violin - is a stand out choice for F Tene as many meta heroes on her release are very buff reliant and the dispel can randomly knock a lot of top tier DPS heroes out of their safety net (R Violet's evasion, T Surin's Stealth)

Fairy Tale for a Nightmare - is her own signature artifact and can be used in conjunction with her S2 in a full control composition to add some chip damage each turn (+15 copy will do 5000 damage to 4 enemies per S2 proc).

Tagehel's Ancient Book - can be considered while not entirely strong on F Tene herself, other control mages can certainly take advantage of the extra souls for more debuff shenanigans and F Tene could once in a while use it for an extra turn to cast a clutch S3.

Sira-Ren - is a decent budget option for players don't might not have the other listed artifacts as it is quite common and even at lower enhancement levels can generously dish out random debuffs to the enemy team though it's very unreliable.
