 Broadly, the \gls{gm} should consider themself bound by the rules as much as the players.
 A good rule of thumb is to make as few decisions as possible, and let yourself focus on description and planning.
 
+\subsubsection{Patterns in the Rules}
+
+Noticing patterns in the rules can help remembering the rules, and making things easier.
+
+\paragraph{Always round up} -- whether someone is helping another character with half their score, or combat calls for half damage, every time someone divides a number, they round up at 0.5.
+One quarter of a +1 bonus is still 0, but half of a +3 bonus is always +2.
+
+\paragraph{Additions half every step} with every rule.
+When team mates add their scores together, the second grants half, and the third grants half again.
+When many people want to combine their Strength scores to lift something, the highest score counts as usual, the second counts at half, then a quarter, an eighth, and so on\ldots
+
+\paragraph{Resting actions allow failure},
+so if someone has to get this spell just right the first time, or judge the chances of a cave-in and commit to a particular tunnel, they do not get a resting action, even if they have a couple of moments to spare.
+
+\paragraph{It's only a Team Roll when experts want to work together}, so if the group ask to make a team roll to craft a fantastic statue, reply `no'.
+Master carvers don't ask for help chiselling their statues, so the roll has to be a Group Roll, i.e. the lowest score can drag everyone down.
+
+Conversely, anyone building a raft would welcome all the help they can get.
+This shows that the group should make a Team Roll.
+
+\paragraph{When in doubt, set the \glsentrytext{tn} high!}
+The standard \gls{tn} of `7' seems like an average, but it functions more like a basic number to add to.
+A professional \gls{npc} would normally have the Specialist Knack,%
+\footnote{See page \pageref{specialist}.}
+granting a +2 bonus.
+A standard horse-trainer should also have Wyldcrafting 1 or 2, as well as an Attributes Bonus, so their total bonus would be +4 or +5.
+
+Finally -- and importantly -- most professionals will perform tasks with a resting action, so we assume they set one die to show `6', and roll the other, for a minimum roll of `7'.
+So professionals can expect to reliably reach a \gls{tn} of 11 or 12, or more with bonuses from equipment.
+
+And if the average professional would struggle with a task, throw them a \gls{tn} of 14!
+
+\paragraph{The dice tell the story}, so if you ever start to panic, have the players make a roll, state any \glsentrylong{tn}, and explain the result.
+A crappy roll to open a door suggests the massive door has wedged properly shut.
+A fantastic roll to talk to the local lord might indicate he has family in that character's home village.
+Explaining results can come easier than making them up.
+
+If you interpret the dice rolls as just how well a character has performed that day, a lot of the system will stop making sense.

 \subsubsection{Let Players `Ruin' the Adventure}
 
-Encounters don't have to play through like you think they do.
-If the players flood a dungeon, cast a fireball at the king, or raise their Wyldcrafting and Aldaron so high they can enchant every wild creature they will ever encounter, take a break, re-examine the situation, and go from there.

+If the players flood a dungeon, cast a fireball at the king, or raise their Aldaron and Wyldcrafting so high that every wild animal encounter turns into a pet in a growing army, take a break, re-examine the situation, and go from there.
 
-Perhaps dungeon has a high-point which isn't flooded, or perhaps it's flooded forever, and nobody will see that treasure again.
+Perhaps the dungeon has a high-point which isn't flooded, or perhaps it's flooded forever, and nobody will see that treasure again.
 Perhaps the party have to become outlaws, and every future adventure has to take this into account.
-Perhaps all encounters with bears, boars, and griffins turn into opportunities for new, temporary pets.
+And even if all those pets feel enamoured with the caster, they don't need to like each other -- maybe they start to fight, or try to kill the other party members, but only when they fall down, wounded and weak!
