Though there are no toggles yet, Invulnerability-Auras now have the option to Drain HP by a % when in their 'hit range' instead of the usual 'instant kill' they're usually known for, if you setvar INVULNHEALTHDRAIN to a value between 1 and 2000, 0 will disable any damage/death, and 2001+ sets it to inflict instant-kills.
Invulnerability Auras can also now be set to deflect a specfic % of the overall damage. The var is called INVULNREFLECTRATE and is set to 1000 by default [meaning 100.0% reflect-damage rate]. Setting it to 0 will outright disable damage reflection, and setting it to any other value sets the reflect-damage rate [although I recommend you don't set it to more than 2000 [200.0%]. :P
If Lisa's Current BioShield energy is 16x her HP and she collides with an Invuln, it will now additionalyl demolish the offending enemy's invulnerablity aura in addition to saving her from death with guarantee.
eduke32.exe and mapster32.exe updated to r4648 [from r4593]

Updates/fixes to the invuln stuff are imminent, as this is the first version of this code. :P
