Twitch and Eve prototype kits, apparently. Stolen from /v/, not sure if real, but interesting either way.
Twitch:
Character Passive: Damage is retaining true and is being lowered a bit. Duration is being increased.
Q: Now a passive/active. Passive is the Xypherous outlined stealth rework. Active grants bonus attack speed for x seconds and instantly reloads x Vile Bolts into Twitch's crossbow.
W: Debilitating Poison: Now requires poison on the target to cast. Cast range increased by double. Can no longer be cast if there are no valid targets in range.
E: New Spell. Fires a narrow line missile instantly that deals total attack damage and includes on hit effects. High range, .75 second cooldown but requires Vile Bolts. Vile Bolts are Twitch's ammo resource that replenishes over time or by reloading via Q.
R: Expunge: Can no longer be cast if there is no target in range. Requires poison, cast range doubled. Damage heavily increased.
Eve:
Passive: Soul Striker: Autoattacks shred flat MR. Spells shred flat Armor. Stacks.
Q: Prana Bolt: Changed to be a pass through missile that seeks its first target in the same way hate spike does.
W: Shadow Stitching. Passive - Bend the Shadows: Xypherous outlined stealth rework. Active - Disperse the Shadows: Evelynn reveals the target area at range for x (scaling) seconds. (scaling range).
E: Ravage Chakra: Evelynn deals damage and instantly stuns the target, dashing towards them immediately after it casts. (Different from leap stuns like pantheon, as it stuns you after they leap to you). No longer shreds armor/mr.
R: Ethreal Ascension: Evelynn ascends to her true form, gains attack speed and movement speed. Upon first transforming she is shrouded in energy and blocks up to X damage for 1.5 seconds. No longer heals on target kill, refreshes on kill
