NOTE:- This mod Impress the companions does the same thing but by increasing the HP instead of level. But in my game I use combat mods so the giant still dies. If you don't have combat mods I would recommend this one instead because otherwise a level 50 giant may be a bit too much for your low leveled character.

This is a simple mod made using creation kit. What it does is change the Giant's minimum level to 50, 60, 70 or 80 depending on the version you get. In the Vanilla game the Giant's minimum level is 10 which means it quickly dies unless you're playing in very high difficulty. Don't let the high level scare you in my game the giant still dies in like 10-15 seconds.

I don't like to play in high difficulty instead I prefer mods like ASIS, AAE, OBIS and combat mods like Wildcat to make things hard. Because of this my difficulty is in Adept usually which means the Giant kept dying very quickly for me and Aela kept berating me through no fault of my own. So this mod is here to change that.

Hope you enjoy using it and let me know if there are any problems.

This mod was made with game version 1.5.73 I think it will work for other versions.
