New user, several questions

I'm sorry for the non-descriptive title, I just don't know what to call it.

Okay, so, here are some of the questions I have. I've tried to work through the things I could, but some problems seem to persist.

1. How do you get a cliff edge to show up? The first scene in the little game I'm making starts on a snowy mountain with several levels of elevation. The ledge tile looks best at the top of a cliff, but when an edge tile meets a cliff tile it looks different than when it meets a snow tile. Heres a picture, in case I'm being confusing.

The bottom is snow, and the middle and to are ledge tiles. But I want the top cliffs to look like the bottom ones. I know I can use snow tiles, and then shift snow/ledge tiles to cover up the ugliness, but it takes too long and gets impractical when I need to move things around. Is there any way I can tell the top cliff to just behave like the bottom cliff?

2. There's a problem with the battles, no one does any damage. For some reason, when I try and do battle tests, nobody ever does damage. Here's screen shots of the unit, the class, the skills, and the battle.

It happens with every enemy I set up. No clue why or how.

3. I haven't gotten this far, because I haven't been able to get battles to work, but is there any way to have characters learn different skills depending on who's in the party? Like, beyond level 15, if Fighter is in the party, then Fighter learns "such and such". Also, is it possible to have an event take place when the character learns that specific skill?

4. What's the best way to edit tiles? I tried to edit the Grass and Dirt Plateaus in A5 to be white, so they could look like snow, but it just didn't come out right. Between it not getting all the green and the edge still not looking like the snow ledge edge, I just couldn't figure out how to do it.

Those are my biggest problems right now. I also don't know how to use regions, but I'll figure that out. There's probably a guide somewhere.

For your snow cliffs, you are using the wrong tiles to back up the first, lower ledge, to the higher ledge.  You are using the top cliff edge, whereas all you need to do is just use snow.  You would use those top tiles if you wanted to show where a ridge of hills finished, not to indicate that it was blending from one ledge to another.

For your zero damage - on the 'Class' tab - if you compare yours with the default one you will see that one element is missing.  the default class tabs have [HIT] + 95%, you don't have anything at all for HIT.  0% Hit rate = will miss all the time; 100% Hit rate = will never miss.  By not having anything there, the engine assumes you mean 0%.

Yes it is possible to have characters learn different skills, but it is not dead easy.  As you are new to using the engine, I suggest you get the basics under your belt before tackling that one.

In the tutorials thread, there is one specifically on making things snowy.  It's here: http://forums.rpgmakerweb.com/index.php?/topic/27789-rtp-editing-make-a-snow-covered-tile/?hl=snow

Andar has complied an excellent thread full of stuff that those new to the engine can use.  Could I suggest that you have a look at it.  Spending time on the fundamentals now will save you a huge amount of time and frustration in the long run.  The thread is here: http://forums.rpgmakerweb.com/index.php?/topic/14727-a-starting-point-for-new-users-v08/?hl=+starting%20+point%20+users

Also you should learn Shift Click mapping too http://forums.rpgmakerweb.com/index.php?/topic/14387-shiftclick-mapping/?hl=shift This could help with some things.

Thank you for the responses!

Hadn't noticed the Hit %.

I learn pretty quickly. I've learned how to use Ren'py well enough to make a full game in a pretty short time. Could you possibly link me to the place that details learning skills at specific times with specific teams so I can bookmark it? I think I'll need it pretty soon, and I don't want to make another thread to ask for it. That specific concept is going to be one of the focal mechanics of the full game I want to make when I'm ready, so it's going to definitely be something I need to learn it.

Thank you for the links. I'll go through all of them.

Thank you. I knew you could shift left click, but I didn't know shift right click followed by shift left click was a thing.
