Countering Eriu

[Sombre]

Glamorous armies are problematic, but the answer in my book is usually just to counter raid them. If they are sneak moving and striking to avoid your countering forces, then they are taking twice as long to grab provinces as normal raiders and thus you can outraid them. If they aren't, the usual tactic of teleporting a killteam on top of them applies.

Mind hunt works even if he is stealthy. Make/Trade for penetration items. Eye of the void, rune smasher, amulet of penetration.Your nation may not have easy access to Astral. But really if you can't at least scratch up an S2 at some point you are going to lose anyway. Just 1 mindhunt a turn with good penetration will ruin his day.

Otherwise, you need to counter raid him with guys who can take a province every turn. (an example would be a bane lord with flying boots,flame brand,lucky shield, amulet of MR, amulet of lightning resistance, jade armor) That guy would be a huge pain for Eriu to try and counter. Force him to keep up with your counter raids. If he takes 1 province then stealths away, thats 1 every other turn. Meanwhile you are taking 1 a turn.
