Confusing language (probably an error) in homing motes

[Daniel-Soham]

Describe the bug
You can increase the number of motes by 2, the damage by 1d8 for each additional mana expended, and the damage by 1d8 for every two additional mana expended.

This looks confusing.

Looking at the spell balance spreadsheet, it seems the idea is indeed that it increases 1.5d8 per mana (or 1 on odd extra mana, and 2 on even mana). I think there must be a better solution for this, perhaps to change the die to 2d4 and increase the damage by 3d4 per mana

[mlenser]

for every two additional mana expended is used commonly - for at least 28 spells. It's a common way to manage the balance.

2d8 + spellcasting does 29.7 damage at 2 mana, 45.2 at 3 mana, 60.6 at 4 mana, and 76.0 at 5 mana. Perfect.
4d4 + spellcasting does 32.0 damage at 2 mana. Just ok. Adding 2d4 means it deals 43.4 at 3 mana and 66.3 at 5 mana. Too low. Adding 3d4 means it deald 49.2 at 3 mana and 83.5 at 5 mana. Too high.

If there is math that makes it scale nicely let me know, otherwise the current implementation is the best we can do for this spell and many others.

Perhaps the wording would be a little clearer if it said and extra 1d8 for every two mana expended for these 28 spells using this wording? As it reads now it looks like something got pasted twice in a row.
