Summary
 
This plugin is an edited version of Level Up Birthsign Remover that addresses a bug when used in conjunction with Talrivian's State-Based HP.
 
If you're using LUBR along with a retroactive health mod like State-Based HP, you'll notice a problem. If you have The Lady birthsign (which boosts endurance by 25), your health will temporarily decrease when you rest (the spell which boosts your endurance is being removed, which lowers your endurance, which means your health is also lowered). If you have low health when you rest, the result is instant death.
 
The minimum safe health upon resting is: 13.5 + 2.5 * (level - 1). In practice, the actual minimum threshold is a bit lower than this, I think because you gain a bit of health through resting before the spell is removed.
 
This edited version of LUBR addresses this problem, at the cost of getting some free healing if you have The Lady birthsign and rest with low health. The script now basically checks your health before removing The Lady's attribute boosts, and if your health is below the minimum safe threshold, it's increased up to the safe value.
 
The additions to the script are as follows:
 
Declares the new variables level (short), and ladythresh, health and modhealth (floats).
 
Adds the following lines before removing spells "lady's...":
 
set health to ( player->gethealth )
set level to ( player->getlevel )
set ladythresh to ( 2.5 * ( level - 1 ) + 13.5 )
set modhealth to ( ladythresh - health )
if ( health < ladythresh )
player->modcurrenthealth, modhealth
endif
 
Installation
 
If you're using Wyre Mash, install this archive in the Installers tab and select the plugin in the Mods tab, like normal. If you're not using Wyre Mash, copy the .esp file to your Data Files directory, and select the plugin in the Morrowind Launcher.
 
This plugin is a replacement for the original Level Up Birthsign Remover, not a patch. Use either the original version, or this version, not both. There's no point using this version of the plugin if you're not also using Talrivian's State-Based HP. If you're not using State-Based HP, use the original version of LUBR instead.
