Simple Anti-Ogre Dice

Continuing my recent (I, II) Ogre obsession... And after bit more discussion about simple Ogre dice, here's another thought. How about Anti-Ogre CR dice?

Why an Anti-Ogre dice?

They can't be used against 'conventional' units, but work well in scenarios where one side consists only of one (or more) Ogre(s); such as 'Mark N Assault'. A player opposing Ogres would only need one type of die - and you may even already have some that will work. ;)

So...

Ogres are unaffected by D results, so only X results are relevant. Following the CRT (including auto success on 5-1+), these occur on a rolls of 6, 5+, 4+, 3+, 2+, and 1+ (auto success).
The custom dice version replaces each facing on the die with the minimum A:D ratio required for success: 1-2, 1-1, 2-1, 3-1, 4-1, 5-1.

So calculate the A-D ratio, then roll the die. If the roll is equal to or below that ratio, the attack succeeds.

Using your own dice

If you have any dice where a logo replaces the 6 (not uncommon, but sadly not the official Ogre dice), then try this:

Referring straight to the calculation of A/D (if that makes any sense), the die needs these sides: 1/2, 1, 2, 3, 4, 5. So if the '6' (or logo) is redefined as '1/2', we 'have' all these numbers.

Examples:

• Attack 5 vs Defense 2: 5/2 = 2.5. If you roll below 2.5 ('1/2', 1 or 2) the attack succeeds! (normally 2-1 on the table, so X on 4, 5, 6)
• Attack 2 vs Defense 3 = 2/3. Only succeeds if you roll '1/2'.
• Attack 8 vs Defence 2: 8/2 = 4 (aka 4-1). If you roll 4 or less (5 in 6 chance), success!

I know some don't like 'roll low', but it avoids table look-ups for one player, who is often the new arrival. You could rationalize it as if you're rolling the Ogre's armor - a low roll means weak armor.
