1. A training roll is how you use tech skills. Roll up to 3 dice (this depends on how many tech skills you know), and if you roll a number that is equal to or less than the current level of that tech skill, then you hit the opponent and level up. Otherwise you miss.
2. In MIRU 2, you don't have to number the village.
Map Decryption can be found on pg. 45. Depending on which map you are trying to decrypt, you'll translate the cryptic language next to the spaces you need to fill out. I can't spoil how to translate the text, but everything you need is in the book. The only hint i feel is appropriate to post publicly is that you should look at the chapter titles. You can use the grid page at the back of the book to take notes for the language.
There are 3 radio towers in MIRU 2. One you'll find after Day 35 and two you'll find in the events (Radio Tower will be in bold).
Oh you're updating your comment! I was like... wasn't there more to answer! Sorry for the late reply, I just got to my computer! Congrats on cracking the code!!!
To decrypt a map, you'll need to be on the radio tower tile. Once you've solved the puzzle, you'll roll 3xD6. Use the priority map on pg05. (So if you roll a 12, the treasure on the map is 2 spaces south of the tile you're on.
There are a few opportunities during different events to interact with a Helper F2. (You may have the option to kill it) With a PDF if you type ctrl+F you can search a document for a word. So if you really want a Helper F-2, see where it pops up in bold and just be on the lookout for that. Just glancing back over everything, i see at least 2 opportunities to interact with a dead Helper F2. Feel free to note on your map after you've killed one so you can go back and visit it if needed.
1. Radio tower counts as an icon on the map yep!
2. You can use the same tower to decrypt all maps. Since that tile is a place you've visited before you would do steps (A-C-H-F-G) the event for the radio tower building would be decrypting the maps. So once you've done those yes, your day would end. (You can do all 3 in the same day)
3. Tiles with a treasure icon on them work like I demonstrated above. A-C-H-F-G. The 'event' is just finding the treasure no exciting text for those im afraid. The decrypted maps should tell you the terrain of the area you unlocked. Basically grab treasure and end the day.
