Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Contract locking ether found:
Contract DragonSlayer (DragonSlayer.sol#14-225) has payable functions:
- DragonSlayer.receive() (DragonSlayer.sol#224)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

DragonSlayer._transfer(address,address,uint256) (DragonSlayer.sol#193-221) uses timestamp for comparisons
Dangerous comparisons:
- antiBotTime > block.timestamp && amount > antiBotAmount && botAddresses[sender] (DragonSlayer.sol#199-201)
Avoid relying on block.timestamp.

DragonSlayer.tokensForMarketing (DragonSlayer.sol#31) is set pre-construction with a non-constant function or state variable:
- MAX_TOKENS_FOR_MARKETING
DragonSlayer.tokensForRewards (DragonSlayer.sol#32) is set pre-construction with a non-constant function or state variable:
- MAX_TOKENS_FOR_REWARDS
DragonSlayer.tokensForAirdrop (DragonSlayer.sol#33) is set pre-construction with a non-constant function or state variable:
- MAX_TOKENS_FOR_AIRDROP
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.
