Cuz it encourages build diversity.
Copypasta
Scylla: Poisoned Tiara tree (her tainted golden headband with the green gem - the lore for me is that the gem used to be blue and symbolize her Naiad powers, with the headband being pure silver. And when she was cursed it transformed into dark gold and paleish green)
T1: Poisoned Tiara
+10 Power, + 6% Movespeed
T2: Tiara of Misery
+25 Power, +12% Movespeed, +5 Penetration.
Passive: Scylla's basic attacks cause "Misery", which stays on the enemy for 6 seconds. If the enemy is hit by her abilities, they take 5% of their max HP as damage.
T2: Tiara of Longing
+15 Power, +12% Movespeed, +8% Lifesteal.
Passive: When an enemy God is damaged by Scylla's abilities, she gains 1% HP per second for 10 seconds. Additional procs refresh this effect.
T3: Tiara of Vengeance
+65 Power, +18% Movespeed, +15 Penetration.
Passive: "Misery" also increases Scylla's Pen to that target by 15% (like Obsidian Shard). This effect remains when Misery is removed for 3 seconds.
T3: Tiara of Bloodlust
+85 Power, +18% Movespeed, +10 Penetration.
Passive: "Misery" now deals 8% HP as Damage and Scylla's CDs are reduced by 1 second when procced.
T3: Tiara of Hunger
+55 Power, +18% Movespeed, +22% Lifesteal.
Passive: While under the effect of "Longing", all of Scylla's abilities lifesteal for the full value regardless of AoE coefficient.
T3: Tiara of Regret
+30 Power, +18% Movespeed, +16% Lifesteal.
Passive: While under the effect of "Longing", all of Scylla's abilities heal nearby allies for 25% of the damage dealt to all Gods hit, + (10 + 4 per level, per God hit) Range 55.

There's lore behind these and their passives. Because I don't do anything halfway XD.
Poisoned Tiara - when she was cursed, her powers changed. From water-based to haunted fire/Greek fire and control over demons.
Tiara of Misery - she's miserable, and blames the Gods for her fate. Thus she deals more damage to everything.
Tiara of Longing - she's miserable, and only wishes to be healed of her curse. Her own attempts fail, only healing her physical wounds and only when she attacks like the monster people make her out to be.
Tiara of Vengeance - She wishes swift and furious death upon anyone who's wronged her. Not even the strongest god will stand in her way, as she seeks vengeance for her fate.
Tiara of Bloodlust - Giving into the curse, she loses whatever goodness she had, and longs only to destroy anything and everything she can, for fun.
Tiara of Hunger - Her desire to be healed is twisted by the curse and causes an insatiable hunger to arise within her. She fights now not for revenge, for salvation, but only to feast, to try and satisfy her unnatural hunger.
Tiara of Regret - She accepts at last that there's no way for her to be saved, and makes her peace with the gods. She does her best to use her powers for good alone. Destroying only those who attack those she calls friends, and healing those friends in their time of need, so they won't end up like her.
