How to Properly add weapons that have special effects

Greetings, I apologize if this has been covered elsewhere, but I'm looking to see how to add, for instance, a sword of lifestealing to my character sheet, so that it will trigger some effect on a crit.  I understand that I could just heal myself, but let's say I have a sword that does 1d6 cold damage on a crit, how would we add that "special" attack on a crit. Thanks, Corey

If you are using the 5e sheet you have an option for that although I don't think you can print the special bonus damage type

If you list the extra damage as +1d6[cold], it will not show on the roll template in the chat display, but it will show when you hover over the roll.

Similar question, but with an armor. How would I add an armor that increase Ac by my INT modifier and increase my speed by 10 feet? Using the 5e sheet of course. I guess you guessed it is for my Bladesinger :P Ac +[@{intelligence_mod}], [@{speed}]+10 This is not working, but I guess I am not that far...

Unless you're using a custom API the character sheet is not setup to handle references inside of Items. You'd have to specify what your current Int bonus is and change it as your Int changes. I'm not sure if the basic version can even do anything to speed.

Aww
