Thats is how add full bless
Code: 
doPlayerAddBlessing(cid, 1)
doPlayerAddBlessing(cid, 2)
doPlayerAddBlessing(cid, 3)
doPlayerAddBlessing(cid, 4)
doPlayerAddBlessing(cid, 5)

Right?

And to remove all blesses?

You need to source edit to make this possible. So what you need to do is add the function to player.h and doPlayerRemoveBlessing to luascript.

Code: 
void addBlessing(int16_t blessing) {blessings += blessing;}
void removeBlessing(int16_t blessing) {blessings -= blessing;}

Code: 
int32_t LuaInterface::luaDoPlayerRemoveBlessing(lua_State* L)
{
//doPlayerRemoveBlessing(cid, blessing)
int16_t blessing = popNumber(L) - 1;
ScriptEnviroment* env = getEnv();
if(Player* player = env->getPlayerByUID(popNumber(L)))
{
if(player->hasBlessing(blessing))
{
player->removeBlessing(1 << blessing);
lua_pushboolean(L, true);
}
else
lua_pushboolean(L, false);
}
else
{
errorEx(getError(LUA_ERROR_PLAYER_NOT_FOUND));
lua_pushboolean(L, false);
}

return 1;
}

to add all blessings:
Code: 
for i = 1,5 do
    doPlayerAddBlessing(cid, [i])
to remove all blessings, dunno if this works but try it:
Code: 
for i = -1,-5 do
    doPlayerAddBlessing(cid, [i])

Blessings is a single column in the database, just set it to its default value 0
Code: 
`blessings` TINYINT(2) NOT NULL DEFAULT 0,

This is how you count backwards
Code: 
for i = 5, 0, -1 do
    print(i)
end
-- output
5
4
3
2
1
0
Code: 
-- default of step is 1
for var = start, stop, step do

I'm genuinely curious though..
When we use
Code: 
for i = 1, 5 do
    doPlayerAddBlessing(cid, i)
end
I assume the default step is +1.
However if it's a single column in the database.. how do we alter each value in the column?
When using the command, it changes each of the 5/6 blessing values..?
Code: 
doPlayerAddBlessing(cid, 1) (change value in row 1, to 1)
.
.
.
doPlayerAddBlessing(cid, 5) (change value in row 5, to 1)

As far as I know, there is no way to alter this number while the player is online.
When player is offline we can do a database query to alter it directly.. but meh
Maybe I'm wrong though.

-- edit --
We can give them blessings while online, but cannot remove the blessings while online currently.

@OP
You can remove them by killing the player. xD (easy solution)

@Xikini
There is no such thing as +1, 1 is always positive, -1 is always negative even when we add 1 + -1 or -1 + 1 always equals 0.
Lets run some tests using the values -1, 1, +1
-1
Code: 
local start, stop, step = 5, 0, -1

for var = start, stop, step do
    print(var .. ' + '.. step ..' = '.. (var + step))
end
-- output
5 + -1 = 4
4 + -1 = 3
3 + -1 = 2
2 + -1 = 1
1 + -1 = 0
0 + -1 = -1
1
Code: 
local start, stop, step = 0, 5, 1

for var = start, stop, step do
    print(var .. ' + '.. step ..' = '.. (var + step))
end
-- output
0 + 1 = 1
1 + 1 = 2
2 + 1 = 3
3 + 1 = 4
4 + 1 = 5
5 + 1 = 6
+1
Code: 
local start, stop, step = 0, 5, +1

for var = start, stop, step do
    print(var .. ' + '.. step ..' = '.. (var + step))
end
-- output
 unexpected symbol near '+'
See :)

Right, I know how to count as well.
1,2,3,4,5,4,3,2,1,0,-1,-2,-3,-4,-5,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5
However, we aren't counting right now.
Code: 
doPlayerAddBlessing(cid, 1)
doPlayerAddBlessing(cid, 2)
doPlayerAddBlessing(cid, 3)
doPlayerAddBlessing(cid, 4)
doPlayerAddBlessing(cid, 5)
This is not counting.
There is 5 different blessings.
If you use only..
Code: 
doPlayerAddBlessing(cid, 5)
It will not work.
Your only giving the player blessing number 5.
Change Blessing 5 to '1' or 'enable'.
You are not adding 5 blessings.

I know you know how to count, i was just giving you an example of the step of a for loop :)

The c++ source of doPlayerAddBlessing, I do understand some of it but not enough to translate to english, so I won't even reference the source, lets just keep it simple :p
