When used without an existing enhancement bonus, everything functions as expected.
However, when combined with an existing one, it applies an HP buffer equal to what the an additional constitution bonus would have given, but the maximum HP isn't affected. When Tenser's Tranformation expires, the user's HP is reduced by this amount. If the user's HP is low enough once this occurs, they may be instantly killed.
There are several problems that can stem from this issue.
- A user unfamiliar with this nuance may be killed by the expiration of Tenser's Transformation when they may otherwise consider themselves safe. Have to admit to having killed myself at least once by resting while both Bear's Endurance and Tenser's Transformation are active, and the combined HP loss of losing both dropped me from about a third health to instant free trip to the Fugue.
- After this extra HP is removed, you still can't heal over your regular max HP, meaning you're essentially functioning with a reduced HP pool as you'll be taking a set amount of damage as soon as Tenser's expires.
- As you are limited to self-healing through Healer's Kits, with potions and other spell-duplicating consumables being useless due to Tenser's overarching spell failure, you may not be able to quickly recover enough HP to avoid death towards the end of the spells duration if you have taken sufficient damage beforehand.
- Using a weapon with Vampiric Regeneration instantly removes this buffer, essentially nullifying any benefit you may potentially get from the bump over your HP maximum to begin with.Hidden: show
Suggestion: Remove Tenser's Transformation +4 Constitution bonus, either when a character already has a CON bonus from another spell/item, or entirely as it would hardly be missed by a class capable of proving a longer-term bonus of this nature by other means. Optionally, if a bonus to resilience is somehow meant to be offered, rather than the risky CON bonus an amount of Temporary HP and/or Fortitude Save bonus may be granted instead.
Thanks!
