In order to track all the conditions, effects, bonuses and penalties that a creature can receive during combat, the Guild uses a custom set of Roll20's status marker system (curated by Ashley). In general, you only need to mark bonuses and effects when they're temporary. If your character has resist 1 all constantly active from a magic item, you don't need to keep a tower symbol on your token at all times to show that, but if a power grants resist all until your next turn, it's worth tracking. Mark/Quarry/Curse/etc There are 15 different colored dots that denote marks, as well as class features like the ranger's quarry or the warlock's curse that care about who applied them. If your PC uses one of these features, you should pick a specific color of dot and leave it on that character's token, so people can see which dot corresponds to which PC. Unconscious Occasionally the red X will also be used to denote a creature that is dead but still on the battle map. Attack Bonus/Penalty The sharp swords are used to show a bonus to attack rolls, while the broken one shows a penalty. By placing a number on the marker (hover your mouse over the marker and press the key for that number instead of clicking on it), you can also show the value of the bonus or penalty. Blinded Bloodied Burrowing/Flying The pickaxe represents a burrowing creature, the wings a flying one. You should also show how many squares above or below the ground your character is by placing a number on the symbol - for example, a wings symbol with a 2 means there are 2 squares between your character and the ground. Can't Shift Concealment Damage Bonus As with attack bonuses, you can place a number on the marker to show the size of the bonus. Dazed Death Saves When you fail a death saving throw, add the skull and crossbones marker to your token and place a number on the marker to track how many death saves you've failed during the current encounter. Defence Bonus/Penalty The intact shield shows a bonus to defences, the broken one a penalty. Dominated Grabbed Grants Combat Advantage The 'flag of shame' indicates a creature that's granting combat advantage. The black flag is used under most circumstances, while the white flag can be used to show conditional combat advantage, such as a creature that only grants combat advantage for the next attack against it, or against adjacent enemies only. Hidden Immobilized Insubstantial Invisible Ongoing Damage The different colored flasks can be used to show different types of ongoing damage. Because ongoing damage almost always comes in multiples of 5, a number is usually added showing the ongoing damage value divided by 5. For example, a creature with a black flask marked with a 3 and a blue flask marked with a 1 might be taking ongoing 15 untyped damage and ongoing 5 cold damage. Petrified Prone Protective Scrolls Some characters hand out consumable protective scrolls to their allies at the start of the adventure, using the runepriest power of the same name. When that happens, you can track how many scrolls each character has using this marker. Psychic Lock The psychic lock feat gives a penalty to the target's next attack roll. The padlock is used to track this and other, less common effects that penalize only the next attack roll the target makes. Regeneration Resistance Usually only resist all is marked - resistances to specific damage types are niche enough that you don't need to remind everyone about them. Restrained Slowed Stunned Transformed/Polymorphed This marker is used for certain wizard powers that transform their targets into small animals or for other polymorph powers. Vulnerable When a creature becomes vulnerable to all damage, the meteor symbol is used. The snowflake and radiation symbols are used to track vulnerability to cold and radiant damage, respectively - the most commonly inflicted vulnerabilities to specific damage types. Weakened Other Markers The remaining markers don't have official uses in the Guild, but can be used as needed to track the effects of more exotic powers or unusual situations.
