Janna

Arena changes

• I: Ally haste changed to 8% bonus movement speed.
• I: On-hit damage movement speed ratio changed to 40% bonus movement speed.
• Q: Base bonus damage per second changed to 20 to 40.
• Q: Bonus damage per second AP ratio changed to 20% AP.²

• Janna’s shield can change Riven’s adaptive power.³
• With Circle of Death, Critical Heal and Shield, an augment that scaled ability haste with AP, and an augment that scaled AP infinitely, casting E every second ended the previous shield while it was nearly full, and the explosive shields dealt over 200k damage.⁴
• Gargoyle and Locket can deal damage in a Janna build where her E shield barely matters.⁵
• For some champions with on-hit passives, including Janna, an omnivamp effect can refresh stacks with on-hit attacks; this interaction does not work on Kai’Sa.⁶
• Janna’s ultimate is a big power spike in Arena.⁷

Earlier formats

• Janna needed an on-hit god roll or a Bel’Veth ally to carry her.⁸ 8x2 duos
