  • I have used both types of distance calculation in different campaigns. I agree that the ‘alternating’ rule is better, but I’ve also seen that it confuses some players and in that case slows down combat.

    I’m currently using the phb rule. My players have just gained access to fireball and similar AoE spells, and I use the actual circular spell effects

    So far I have not seen the players actively abusing this, so for now I’m just ignoring the weird distance effects


  • Mathematically, a circle is defined by all points that have the same distance to the center point. In d&d on a grid, distances are measured in 5ft squares, where a diagonal distance is the same as an orthogonal distance. This results in mathematical circles being square on a 5e/5.5e d&d grid

    so, one fireball, having a mathematical 20 ft radius, can completely fill a square room of 40x40 ft.

    Yes I know the book has a circular template for spell effects. However, using that on a grid has the weird effect that a target can be in a place that is 20 ft removed from the center (diagonally) but at the same time not be in the area of effect of a fireball cast on that center point





















  • Good question. So, perform an experiment: put an ice cube without air bubbles in a glass containing a mixture of ice and cold water. The temperature should become 0°C (just before it freezes), measure it.

    Your hypothesis: ice is heavier than water, so it will sink

    Execute the test several times, preferably 10 times or more. More is better.

    Please share your experiment results. Interesting data to know for each test would include:

    • sequence number of the test
    • temperature of the mixture before and after you put the ice cube in
    • method of ice cube creation
    • volume of the ice cube
    • volume of water/ice mixture
    • depth of the water/ice mixture (should be > size of the ice cube)
    • type of water used (tap, bottled, …)
    • did the ice cube sink
    • if no, what volume of the cube remained above the surface level

    please also share your conclusion.
