5e House Rules

Creation
Point-buy will be slightly more powerful. Will allow up to 17, albeit expensively; and 16 will be reasonable, but you might not be able to get two of them.

If you choose to roll, I'm not gonna lock you down to the first one if it's terrible.

Delay
"Delay", from 4th ed, exists. This is different from "Ready an action". When you delay, you do nothing with your turn. Good effects that expire "on your turn" expire, but bad effects continue until you actually have your turn. You are taking yourself out of the initiative order and can jump in after someone else's turn happens. Thereafter, you are at that point in the initiative order.

Wizard
The # of cantrips listed as "known" are the ones you have prepared; High Elves get a bonus prepared slot.

Your initial cantrips are in your spellbook, you can add cantrips to your spellbook by the same methods as other spells.

You re-prepare cantrips, if desired, when you re-prepare other spells

Cantrips count as 1/2 level spells for purposes of "Overchannel."

Stealth and Surprise
Creatures do not have facing in combat -- they are considered to be attentive on all sides. However, creatures may have facing outside of combat, including for ambush/surprise purposes just before combat. Creatures actively standing watch have disadvantage to perception checks in a 180 degree arc to their back (or a -5 on passive perception). Creatures not actively standing watch do not get a perception check in a 180 degree arc to their back.

Most characters cannot maintain constant omnidirectional alertness for more than five or ten minutes without becoming too mentally fatigued to continue. However, the "Alert" feat grants a character the ability to maintain combat-like universal facing for two hours (i.e. the standard watch duration during a long rest).

Sneaking past enemies without attempting an ambush can use the "group check" mechanic for stealth; i.e. if the median member of the group beats the best perception of the enemy group then the check is perception. Ambush attempts, however, pit the worst stealther involved against all the passive perceptions of the ambushees.

AMENABLE TO CHANGE: Hiding when no one can see you. Can you re-hide over and over? If so, monsters can too which means they'd probably do worse things to parties. 2 options: allow it, OR, only roll hide at the point of opposed check. What do you think?
