How I know how much mana I have?
 

LV 28 human necro at moment, I need to do math to know my maximum mana. Eg - Start to cast an spell with 100 mana cost and if I lost 12% of my mana, I can do the math and reach the result that I have 833 mana.

Any way to confirm it? Pressing "I" doesn't show my mana, only hp

The shitty default UI doesn't show much information, look into another UI like Duxa or many others, those show precise experience, health, mana information etc. You can also create a magelo profile of a character on the p99 wiki, put whatever gear or lack thereof you want on it, and see the total stats, it's not 100% accurate but it's close.

Further, you can also find int/wis to mana formulas on the wiki if you search statistics or intelligence :)

HOw I install an different UI? And will work in Archlinux + Wine?

Wherever you have EQ installed, there's a uifiles folder, download duxaui and put the duxa folder into the uifiles folder, then load it in-game. If it's not working, replace the contents of the velious folder in uifiles, with the duxa files.

can also just /load duxa

dont have to download anything

Uhh, duxa doesn't come with p99 or EQ titanium files, you'll have to download duxa ui files.

But yes, /load duxa would work if you have the duxa folder in your uifiles folder.

Duxa UI is so nice. I highly recommend it.

It's great for showing EXP percentage, health and mana numbers, spell gem names, and it's great for clickies as it shows your inventory at all times.
