They are performed in secret with the DM
The Monk's Feature "Deflect Missiles" will also apply to any ally that is within 5 feet of you.
The DM will be in charge of informing players when to level up. A record of the sessions is kept to calculate the experience. Solving problems in creative ways, making important decisions in character, and thinking outside the box will be rewarded with a mark, two marks are equal to a session's worth of experience.
When leveling up, new features, spell slots, and options will come into effect after the next required rest, in case the level up occurred out of a rest.
You can fall unconscious 1 time per Long Rest without consequences. After that, falling unconscious adds 1 level of Exhaustion (PHB p.291)
A resurrection ritual will be performed when a spell is used that takes more than one action to cast. In which after completion, the DM will roll 1d20 to determine the effectiveness of the ritual, based on ability checks made during the ritual. This ritual changes depending on the time it takes to cast the spell.
Anyone who can cast, can read a scroll, with the following limitations, the origin of the magic must match, arcane casters can not read scrolls of Clerics, Druids, Hunters or Paladins and vice versa; if the spell is not on the list of who reads it, the check is done with disadvantage if it's of a higher level than it can be cast, if not, a normal check is made, the rest of the normal rules of scrolls continue to apply.
The triple advantage will be used to reward teamwork and plans as a whole, triple advantage will be the same as the normal advantage only with 3d20 instead of 2d20. If in a combat several people coordinate to perform an action instead of just attacking again and again, that action could have triple advantage.
Critical damage is maximized
(a crit with a greatsword and +2 to Str modifier would be 12 + 2 + 2d6)
