Tether's sub-spell has only 1 level, causing several issues
Sub-spells usually have the same amount of levels than the spell they belong to. Their level is automatically set equal to the main spell. However, Tether's sub-spell has only 1 level, causing the following issues:
- ALT-clicking on Tether while its sub-spell is active always shows level 1 as its level in the chat, regardless of which level Tether actually is.
- Illusions created of Io while Tether's sub-spell is active always have level 1 Tether, regardless of which level Tether is on the main hero.
- Tether cannot be leveled up while the sub-spell is active, getting the "Ability Is At Max Level" error message, even when Tether is not on level 4 yet.
Other spells with the same issue are Ice Blast
and Song of the Siren
