Actually, using a poison gas spell or potion at the wall can be a possible strategy. Create the poison gas cloud, move out of the way, and the enemy will need to move into the gas cloud in order to melee attack you.

Honestly, I wonder why these mechanics you should never use are even a thing. Why have a constly HP restoring mechanic when magic can be restored for free and there are healing spells (one of which you can even start play with)?

Edit: Why the low rating? What did I do wrong here?

Well unless you're fighting a god/deity(or some person in ugly spandex), that is. ;)
===============================================

Sounds like a sound strategy, though by weapons in that bit you replied to I meant like rocket launchers/grenade launchers/etc...not ANY weapons whatsoever. :)

Maybe for those with low/no mana and to give the player a bit more of an edge?

On-topic(So I don't derail too much):

Never go to Punxsutawney on Feb 2nd if you're BIll Murray.

Never go to a chocolate factory run by a strange man dressed in purple if you're a "bad" person.

Never start flipping levers on a death ray machine in a 70's themed house if you're angry(or don't make said people flipping people angry if one is strapped to said ray/device).

My bad, I meant in all games in general.

How does having an extra healing method hurt the player?

I dunno....but they likely expect people to write them down.

Because it's a trap. Using it not only costs money and takes a fair amount of real time, but it also ages the character if done too much, which increases the likelihood that your stats will drop at level up.

If you're going to put an inn in your game, do it the way JRPGs handled it; one trip should fully restore the whole party for a nominal fee. Don't make the player wait for hit points to be restored (or else use spells and then rest again), and certainly don't permanently age the character for doing so.

(Another game with spectacularly poor healing options is Pool of Radiance, though unlike Wizardry resting doesn't cost or age (but is still slow), but there's no full heal spell to save you from the tedium of healing later in the game.)

But you might run into games where doing so is actually a good idea.

In some games, for example, you become invincible after taking damage, so hitting yourself weakly can make you invincible just long enough to avoid a more dangerous attack. In others, taking damage knocks you back, and that knock back can be used to your advantage, to reach places that you wouldn't otherwise be able to. (See damage boosting and rocket jumping for examples of this sort of thing.) There are even games where there are advantages to being near death or disadvantages to being healthy. (For example, in Mario games, small Mario can fit in places that Super Mario can't; if you are playing troll levels (Mario Maker) or hacks, sometimes you need to intentionally take a hit in order to progress.)

Never play fortnite, it is just a bad idea.

Never be remembered for being forgetful.

Didn't know that - cool stuff :-)

Never expose, to the public internet, a computer with an ssh server running (with password authentication enabled, which is the default) that has a user named "pi" with the password "raspberry". (It's likely OK if you are behind a NAT, like if you have a wifi router at home (your IP address will likely start with 192.168), as long as you don't forward port 22 to it.)

Maybe, but often enough(in normal play) it's a bad idea....so much so that I feel that it fulfills the requirement(for this thread) of being usually a bad idea. ;)

My bad once again, I thought you meant parties moving around and gaining health back like in some games where it happens and there is no negative drawback to it. :)

Never cross the streams.

Gave me a good chuckle because reminded me fellow Goggers posting over there on a certain discussion I was following, and one in particular was being incredibly helpful in actually providing links to games here. Needless to say that didn't go down too well with some mod (see picture).

Dunno if he mentioned that warning and got banned for it, since a few there got warned they could get banned if they told others that they got warnings, and why they did ! My head hurts...

Here's another one:

When programming in C, *never* call the gets() function.

(How a function as atrocious as gets() ended up in the standard C library is beyond me; that function is so bad that it should have been fixed or removed from the standard back in 1989.)

(Can you believe that ANSI C turned 30 last year?)

NEVER! Tell to a girl... That her eyes are like octopus' eyes!

PLEASE MERCY

HEEELLLP

Never talk the talk if you can't walk the walk.
